Getting the Click event of an TemplateField

C

Class

Hi all,

I create a gridview dynamicly because I don't know the columns in advance.
I use the Templatefield to create a linkbutton.
Everything fine..I have the postbackurl and it works.
But now I need to do some extra stuff in the click event of the created
linkbutton.
I tried to assign a delegate to the linkbutton's click event but I never
gets in the procedure I assign.
How can I trap the click event?

Thank you.

Here is the code:

private void CreateGrid()
{
//Create the grid:

foreach (DataColumn col in dtt.Columns)

{

if (col.ColumnName.Equals("FakAID") || col.ColumnName.Equals("markID") ||
col.ColumnName.Equals("FilID"))

continue;

if (col.ColumnName.Equals("Invoice"))

{

TemplateField tempColumn = new TemplateField();

tempColumn.HeaderText = col.ColumnName;

tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screen.aspx?nav=1&tab=I&cid=", "markID");

grvSearchResult.Columns.Add(tempColumn);

}

else if (col.ColumnName.Equals("File"))

{

TemplateField tempColumn = new TemplateField();

tempColumn.HeaderText = col.ColumnName;

tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screen.aspx?nav=1&fid=", "FilID");

grvSearchResult.Columns.Add(tempColumn);

}

else if (col.ColumnName.Equals("Customer"))

{

TemplateField tempColumn = new TemplateField();

tempColumn.HeaderText = col.ColumnName;

tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screent.aspx?nav=1&cid=", "FakID");

grvSearchResult.Columns.Add(tempColumn);

}

else

{

BoundField boundColumn = new BoundField();

boundColumn.DataField = col.ColumnName;

boundColumn.HeaderText = col.ColumnName;

grvSearchResult.Columns.Add(boundColumn);

}

}

grvSearchResult.DataSource = dtt;

grvSearchResult.DataBind();
}


#region LinkButtonTemplate

public class LinkButtonTemplate : ITemplate, INamingContainer

string theColumnName = "", thePostBackUrl = "", theColumnCommandArg = "";

public LinkButtonTemplate(string ColumnName, string PostBackUrl, string

Please find fixed code below. Two things, 1. you have to create grid on init
event handler, 2. bind data only once (IsPostBack == false)

protected void Page_Init(object sender, EventArgs e)
{
CreateGrid();
}

public DataTable GetData()
{
DataTable t = new DataTable();

t.Columns.Add("Id", typeof(int));
t.Columns.Add("Name", typeof(string));
t.Columns.Add("Invoice", typeof(string));
t.Columns.Add("MarkID", typeof(int));

for (int i = 0; i < 10; i++)
{
string str = i.ToString();
DataRow r = t.NewRow();
r[0] = i;
r[1] = "name" + str;
r[2] = "inv" + str;
r[3] = i;
t.Rows.Add(r);
}

return t;
}

private void CreateGrid()
{
DataTable dtt = GetData();

foreach (DataColumn col in dtt.Columns)
{

if (col.ColumnName.Equals("FakAID") || col.ColumnName.Equals("markID") ||
col.ColumnName.Equals("FilID"))

continue;

if (col.ColumnName.Equals("Invoice"))
{

TemplateField tempColumn = new TemplateField();

tempColumn.HeaderText = col.ColumnName;

tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screen.aspx?nav=1&tab=I&cid=", "markID");

grvSearchResult.Columns.Add(tempColumn);

}

else if (col.ColumnName.Equals("File"))
{

TemplateField tempColumn = new TemplateField();

tempColumn.HeaderText = col.ColumnName;

tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screen.aspx?nav=1&fid=", "FilID");

grvSearchResult.Columns.Add(tempColumn);

}

else if (col.ColumnName.Equals("Customer"))
{

tempColumn.HeaderText = col.ColumnName;

tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screent.aspx?nav=1&cid=", "FakID");

grvSearchResult.Columns.Add(tempColumn);

}

else
{

BoundField boundColumn = new BoundField();

boundColumn.DataField = col.ColumnName;

boundColumn.HeaderText = col.ColumnName;

grvSearchResult.Columns.Add(boundColumn);

}

}

if (!IsPostBack)
{
grvSearchResult.DataSource = dtt;
grvSearchResult.DataBind();
}
}


#region LinkButtonTemplate

public class LinkButtonTemplate : ITemplate, INamingContainer
{

string theColumnName = "", thePostBackUrl = "", theColumnCommandArg = "";

public LinkButtonTemplate(string ColumnName, string PostBackUrl, string
ColumnCommandArg)

thePostBackUrl = PostBackUrl;

theColumnCommandArg = ColumnCommandArg;

}

{

LinkButton lnk = new LinkButton();

container.Controls.Add(lnk);

lnk.DataBinding += new EventHandler(lnk_DataBinding);
lnk.ID = "idx";
lnk.Click += new EventHandler(lnk_Click);

}

void lnk_Click(object sender, EventArgs e)
{
// event handler will execute now
}

void lnk_DataBinding(object sender, EventArgs e)
{

LinkButton lnk = (LinkButton)sender;
DataRowView drv = (DataRowView)((GridViewRow)lnk.NamingContainer).DataItem;
lnk.Text = drv[theColumnName].ToString();
//lnk.PostBackUrl = thePostBackUrl + drv[theColumnCommandArg].ToString();

Hi Milosz,

WOW! great help thank you alot!
I understand what you mean with the user control way.

One more thing. This is on a search page and after clicking the search
button I know what to search for.
Then I create the grid.
But that's after the Page_Init and Page_Load.
Is there something I can do about that?

Thanks again.

Hi Milosz,

great thanks for the help I will try it.
One more thing the click event will be in the Template class.
How do I get it to be in the Page?
I want to use the LinkButtonTemplate class in more pages and grids.

Thank you.

Hi all,

I create a gridview dynamicly because I don't know the columns in
advance.
I use the Templatefield to create a linkbutton.
Everything fine..I have the postbackurl and it works.
But now I need to do some extra stuff in the click event of the
created
linkbutton.
I tried to assign a delegate to the linkbutton's click event but I
never
gets in the procedure I assign.
How can I trap the click event?

Thank you.

Here is the code:

private void CreateGrid()
{
//Create the grid:

foreach (DataColumn col in dtt.Columns)

{

if (col.ColumnName.Equals("FakAID") || col.ColumnName.Equals("markID")
||
col.ColumnName.Equals("FilID"))

continue;

if (col.ColumnName.Equals("Invoice"))

{

TemplateField tempColumn = new TemplateField();

tempColumn.HeaderText = col.ColumnName;

tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screen.aspx?nav=1&tab=I&cid=", "markID");

grvSearchResult.Columns.Add(tempColumn);

}

else if (col.ColumnName.Equals("File"))

{

TemplateField tempColumn = new TemplateField();

tempColumn.HeaderText = col.ColumnName;

tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screen.aspx?nav=1&fid=", "FilID");

grvSearchResult.Columns.Add(tempColumn);

}

else if (col.ColumnName.Equals("Customer"))

{

TemplateField tempColumn = new TemplateField();

tempColumn.HeaderText = col.ColumnName;

tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screent.aspx?nav=1&cid=", "FakID");

grvSearchResult.Columns.Add(tempColumn);

}

else

{

BoundField boundColumn = new BoundField();

boundColumn.DataField = col.ColumnName;

boundColumn.HeaderText = col.ColumnName;

grvSearchResult.Columns.Add(boundColumn);

}

}

grvSearchResult.DataSource = dtt;

grvSearchResult.DataBind();
}


#region LinkButtonTemplate

theColumnName = ColumnName;

thePostBackUrl = PostBackUrl;

theColumnCommandArg = ColumnCommandArg;

You have to recreate the grid because criteria have changed:

protected void SearchButton_Click(object sender, EventArgs e)
{
string criteria = txtCrieria.Text;
// get data source based on carent criteria
CreateGrid();
}

Hi Milosz,

WOW! great help thank you alot!
I understand what you mean with the user control way.

One more thing. This is on a search page and after clicking the search
button I know what to search for.
Then I create the grid.
But that's after the Page_Init and Page_Load.
Is there something I can do about that?

Thanks again.
