ASP.NET 1.1 Converted Projet : Datagrid problem

O

Olivier Matrot

Hello,
I've converted an existing ASP.NET 1.1 project to Visual Studio 2005.
There is a problem with the Datagrid control. The Update & Cancel commands
are not working anymore (Edit is working).

Ive noticed that the postback generated javascript has changed since
ASP.NET 1.1. For Example in ASP.NET 1.1, the Updade shortcut
is "javascript:__doPostBack('dgReceivedHistory$_ctl3$lbValidate','')"
In 2.0 it is now "javascript:__doPostBack('lbValidate','')".
The main differences is that there is no more reference to the datagrid in
the client ID of the control...

Any help apreciated.
TIA.

Hi Steven,

After looking at your sample, here are my comments :
1) I'm not using an AutogeneratedColumns datagrid.
2) Bound columns are converted into templates to be customized.
3) I'm not using the ItemCommand Event Handler.

I 'll try to reproduce the problem with your page.
In the meantime, here are some additonnal informations :

Here is the datagrid tag :
<asp:datagrid id="dgReceivedHistory" runat="server" Font-Names="Arial"
Font-Size="8pt" AllowSorting="True"
GridLines="None" AllowPaging="True" AutoGenerateColumns="False"
CellPadding="5" BorderStyle="None" PageSize="15"
Height="10px" meta:resourcekey="dgReceivedHistoryResource1">

Here is te converted datagrid template column :

<asp:TemplateColumn SortExpression="Edit">
<HeaderStyle Wrap="False"></HeaderStyle>
<ItemStyle Wrap="False"></ItemStyle>
<ItemTemplate>
<asp:ImageButton id="ibModify" runat="server"
ImageUrl="img/modify.gif" CommandName="Edit" ToolTip="Modifier l'objet"
CausesValidation="False"
meta:resourcekey="ibModifyResource1"></asp:ImageButton>
</ItemTemplate>
<FooterStyle Wrap="False"></FooterStyle>
<EditItemTemplate>
<asp:LinkButton onkeypress="if((event.which && event.which ==
13) || (event.keyCode && event.keyCode == 13))
{ClickButton(event,'lbtnSubmit');return(false);}"
id="lbValidate" runat="server" Text="Valider"
CommandName="Update"
meta:resourcekey="lbValidateResource1"></asp:LinkButton>
<asp:LinkButton id="lbCancel" runat="server" Text="Annuler"
CommandName="Cancel" CausesValidation="False"
meta:resourcekey="lbCancelResource1"></asp:LinkButton>
</EditItemTemplate>
</asp:TemplateColumn>

In the class file, here is the content of InitializeComponent() :
....
this.dgReceivedHistory.CancelCommand += new
System.Web.UI.WebControls.DataGridCommandEventHandler(this.dgReceivedHistory_CancelCommand);
this.dgReceivedHistory.EditCommand += new
System.Web.UI.WebControls.DataGridCommandEventHandler(this.dgReceivedHistory_EditCommand);
this.dgReceivedHistory.UpdateCommand += new
System.Web.UI.WebControls.DataGridCommandEventHandler(this.dgReceivedHistory_UpdateCommand);

And the associated Edit function :
private void dgReceivedHistory_EditCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
....
dgReceivedHistory.EditItemIndex = e.Item.ItemIndex;
....
}

TIA.

Steven,

I have found the problem modifying your sample to reach the same
functionnality in my project. My fault.

I'm using the event "ItemCreated" to set the focus to the first edit
control. This is done sending the corresponding javascript code with
Respone.Write().

This breaks the Postback generated code.
How can I automatically set the focus to the control with an alternate
method ?
TIA.

Hi Olivier,

Thanks for your response. Glad that you've made some progress. As for the
using Response.Write to output some client script for setting focus, would
you provide some further description on this or the complete code snippet
that can demonstrate the behavior you mentioned? BTW, in ASP.NET 2.0 , the
Page class has the "SetFocus" method which can accept a control instance or
clientID as paramter so that the page will register the proper client
script for us, does this function meet your requirement or there is any
further concerns in your case? Please feel free to let me know.

Thanks,

Steven Cheng

Hi Steven,

Page.SetFocus is usefull.

1) I also need to select the text in the control. This was done by injecting
the following code :
StringBuilder js = new StringBuilder();
js.AppendFormat("<SCRIPT language='JavaScript'
event='onload'
for='window'>document.all('{0}').focus();document.all('{0}').select();</SCRIPT>",
subjectUpdated.ClientID);
Response.Write(js.ToString());

Again using this code breaks the Postback ! Is there something available
with ASP.NET 2.0 ?

2) Finally, I need to Set a default button (the update link) for the form
that is is created by the framework. This was done with the following code
and associated jscript :

textControl.Attributes.Add("onkeydown", "fnTrapKD('" +
defaultButton.UniqueID + "',event)");
thisPage.RegisterStartupScript("ForceDefaultToScriptImage",
defaultButtonScript);

------

defaultButtonScript = "<SCRIPT language=""javascript"">

<!--

function fnTrapKD(btnID, event){

btn = findObj(btnID);

if (document.all){

if (event.keyCode == 13){

event.returnValue=false;

event.cancel = true;

btn.click();

}

}

else if (document.getElementById){

if (event.which == 13){

event.returnValue=false;

event.cancel = true;

btn.focus();

btn.click();

}

}

else if(document.layers){

if(event.which == 13){

event.returnValue=false;

event.cancel = true;

btn.focus();

btn.click();

}

}

}

function findObj(n, d) {

var p,i,x;

if(!d)

d=document;

if((p=n.indexOf(""?""))>0 && parent.frames.length) {

d=parent.frames[n.substring(p+1)].document;

n=n.substring(0,p);

}

if(!(x=d[n])&&d.all)

x=d.all[n];

for (i=0;!x&&i<d.forms.length;i++)

x=d.forms[n];

for(i=0;!x&&d.layers&&i<d.layers.length;i++)

x=findObj(n,d.layers.document);

if(!x && d.getElementById)

x=d.getElementById(n);

return x;

}

// -->

</SCRIPT>"


I already know that there is a new property to to that for the form tag in
ASP.NET 2.0. Unfortunately, the form is generated by the framework when you
click the Edit button. Is it possible to access it from the ItemCreated
Event ?

TIA.

Thanks for your quick response Olivier,

Some comments regarding on your further description on your problem page:

1. We do not recommend use "Response.Write" to register script code or
script block in the page's response html content because "Response.Write"
directly write content into the response stream and is not rendered within
the html body ... so we can not gurantee it always work correctly.

2. For registering script which will be executed right after the page
render out at client, we suggest use Page.RegisterStartupScript, for
registering script block (helper script functions....), we suggest use
Page.RegisterClientScriptBlock function.

In 2.0, they're still available for backward compatiblilty, however, we
suggest you change them to the Page.ClientScript.XXX functions instead.

And as for your current problem page, I've built a new test page according
to your scenario. Instead of registering the script functions in
ItemCreated( I don't think that's the right place since the DataGridItem is
not added into parent control collection at that time...), I register the
script in ItemCommand after performing DataGrid.DataBind() ..... (Of
course I use the function mentioned above to register the script code....)

After converting the page in VS.NET 2005 to 2.0, I haven't met any problem,
it still works well. I've attached the new pages(1.0 and 2.0) in this
message. You can have a reference to see whether it helps. If there're
anything unclear, please feel free to let me know.

Thanks & Regards,

Steven Cheng

Olivier Matrot

Hi Steven,

Thanks for your answers.
I'm using you functionr "RegisterScriptForEditItem" in the ItemDataBound
Event Handler and it is working fine.

Thanks !

Steven Cheng said:
Thanks for your quick response Olivier,

Some comments regarding on your further description on your problem page:

1. We do not recommend use "Response.Write" to register script code or
script block in the page's response html content because "Response.Write"
directly write content into the response stream and is not rendered within
the html body ... so we can not gurantee it always work correctly.

2. For registering script which will be executed right after the page
render out at client, we suggest use Page.RegisterStartupScript, for
registering script block (helper script functions....), we suggest use
Page.RegisterClientScriptBlock function.

In 2.0, they're still available for backward compatiblilty, however, we
suggest you change them to the Page.ClientScript.XXX functions instead.

And as for your current problem page, I've built a new test page according
to your scenario. Instead of registering the script functions in
ItemCreated( I don't think that's the right place since the DataGridItem
is
not added into parent control collection at that time...), I register the
script in ItemCommand after performing DataGrid.DataBind() ..... (Of
course I use the function mentioned above to register the script
code....)

After converting the page in VS.NET 2005 to 2.0, I haven't met any
problem,
it still works well. I've attached the new pages(1.0 and 2.0) in this
message. You can have a reference to see whether it helps. If there're
anything unclear, please feel free to let me know.

Thanks & Regards,

Steven Cheng

| Hi Steven,
|
| Page.SetFocus is usefull.
|
| 1) I also need to select the text in the control. This was done by
injecting
| the following code :
| StringBuilder js = new StringBuilder();
| js.AppendFormat("<SCRIPT language='JavaScript'
| event='onload'
|
for='window'>document.all('{0}').focus();document.all('{0}').select();</SCRI
PT>",
| subjectUpdated.ClientID);
| Response.Write(js.ToString());
|
| Again using this code breaks the Postback ! Is there something available
| with ASP.NET 2.0 ?
|
| 2) Finally, I need to Set a default button (the update link) for the
form
| that is is created by the framework. This was done with the following
code
| and associated jscript :
|
| textControl.Attributes.Add("onkeydown", "fnTrapKD('" +
| defaultButton.UniqueID + "',event)");
| thisPage.RegisterStartupScript("ForceDefaultToScriptImage",
| defaultButtonScript);
|
| ------
|
| defaultButtonScript = "<SCRIPT language=""javascript"">
|
| <!--
|
| function fnTrapKD(btnID, event){
|
| btn = findObj(btnID);
|
| if (document.all){
|
| if (event.keyCode == 13){
|
| event.returnValue=false;
|
| event.cancel = true;
|
| btn.click();
|
| }
|
| }
|
| else if (document.getElementById){
|
| if (event.which == 13){
|
| event.returnValue=false;
|
| event.cancel = true;
|
| btn.focus();
|
| btn.click();
|
| }
|
| }
|
| else if(document.layers){
|
| if(event.which == 13){
|
| event.returnValue=false;
|
| event.cancel = true;
|
| btn.focus();
|
| btn.click();
|
| }
|
| }
|
| }
|
| function findObj(n, d) {
|
| var p,i,x;
|
| if(!d)
|
| d=document;
|
| if((p=n.indexOf(""?""))>0 && parent.frames.length) {
|
| d=parent.frames[n.substring(p+1)].document;
|
| n=n.substring(0,p);
|
| }
|
| if(!(x=d[n])&&d.all)
|
| x=d.all[n];
|
| for (i=0;!x&&i<d.forms.length;i++)
|
| x=d.forms[n];
|
| for(i=0;!x&&d.layers&&i<d.layers.length;i++)
|
| x=findObj(n,d.layers.document);
|
| if(!x && d.getElementById)
|
| x=d.getElementById(n);
|
| return x;
|
| }
|
| // -->
|
| </SCRIPT>"
|
|
| I already know that there is a new property to to that for the form tag
in
| ASP.NET 2.0. Unfortunately, the form is generated by the framework when
you
| click the Edit button. Is it possible to access it from the ItemCreated
| Event ?
|
| TIA.
