Hi all,

What if i want to add 2 or more control in 1 TemplateField? is that possible? Example is this markup

<asp:TemplateField HeaderText="Overall Margin">

<asp:Label ID="lblOverallMargin" runat="server" />

</ItemTemplate>

<asp:TextBox ID="txtOverallMargin" runat="server" />

</EditItemTemplate>

</asp:TemplateField>

is it possible to do this in Code Behind? 1 templatefield has ITEMTEMPLATE and EDITITEMTEMPLATE.

thanks!!

Hi anil,

you bind the value of the editItem to a readOnlyItem (Label).

So you have to implement the method:

"private void OnDataBinding(object sender, EventArgs e)"

with the Case ListItemType.Item

Then you can use the label for retrieving data from the desired field on RowUpdating.

cheers

{

string errorMsg = string.Empty;

LblMessage.Text = string.Empty;

try

{

Session["InvTable"] = null;

LoadDynamicInvenCalGrid();

}

catch (Exception exp)

{

// Log the exception.

eAdmLogger.ExceptionLog(exp, Constants.CONFIG_EXCEPTION_POLICY, base.userID, base.appName,

Request.UserHostAddress, serverIP, Request.Url.AbsoluteUri);

//Display the message to the user

BuildLabelErrorMessage(exp.Message);

}

#endregion

#region Create Dynamic GridView

/// <summary>

/// This mehod is for Assign the header text value and create the item template,edittemplate dynamically for the grid view

/// </summary>

public void LoadDynamicInvenCalGrid()

try

{

DateTime posdate = DateTime.MinValue;

DataTable dt = new DataTable();

PositionSystemControlBLManager scBLManager = new PositionSystemControlBLManager();

InvenCalGrid.Columns.Clear();

if (InvenCalPosDate.Text != "")

{

posdate = Convert.ToDateTime(InvenCalPosDate.Text.Trim());

posdate = posdate.AddDays(-1);

}

if (Session["InvTable"] == null)

Thanks for the nice article..

i have an issue. please someone help to resolve this,

After postback, the itemtemplate column disappears, if i write under not postback and even i reassign the itemtemplate column in button click event.

if (!Page.IsPostBack)

{

ItemTmpField = new TemplateField();

// create the header

ItemTmpField.ItemTemplate = new DynamicallyTemplatedGridViewHandler(ListItemType.EditItem, dt.Columns[1].ColumnName, dt.Columns[1].DataType.Name);

GridView1.Columns.Add(ItemTmpField);

GridView1.DataSource = dt;

GridView1.DataBind();

}

i need to take the value from textbox to str (which is a control in itemtemplate) from my button click. but while postback, the column itself getting hide. but i try to rebind the data and itemtemplate contorl in my button click, eventhen the itemtemplate is not get binding,

protected void Button1_Click(object sender, EventArgs e)

{

string str = ((TextBox)GridView1.Rows[0].Cells[0].FindControl("ID5")).Text;

ItemTmpField = new TemplateField();

DataTable dt = Session["dt"] as DataTable;

ItemTmpField.ItemTemplate = new DynamicallyTemplatedGridViewHandler(ListItemType.EditItem, dt.Columns[1].ColumnName, dt.Columns[1].DataType.Name);

GridView1.DataSource = dt;

GridView1.DataBind();

}

1) i need to have the itemtemplate column even after postbacking

2) i need to get the value from control in the itemtemplate column while button click

could anyone please help me to solve this two issues.

Thanks in advance.

Hey Brian,

first thanks for your support. Here is a little example how you get DropDown To work:

First of all you have to made a new switch-case construct below this: case ListItemType.EditItem:

Made a case for e.g. DropDown here is a example with a enum as dataSource:

DropDownList Select_List2 = new DropDownList();

Select_List2.ID = FieldName;

Select_List2.SelectedIndexChanged += new EventHandler(DropDownList_SelectedIndexChanged);

Select_List2.AutoPostBack = true;

Select_List2.Attributes["ctx"] = "PrintLocation";

Select_List2.Width = 150;

Select_List2.DataSource = Enum.GetNames(typeof(PrintLocation));

Select_List2.DataBind();

Select_List2.DataBinding += new EventHandler(Select_List_Click);

Container.Controls.Add(Select_List2);

At least you have to call this line for dropDown in EditTemplate:

// create ItemTemplate

ItemTmpField.ItemTemplate = new DynamicallyTemplatedGridViewHandler(ListItemType.EditItem,

dt.Columns.ColumnName, "DropDown");

greets

In edit mode, instead of binding to a TextBox, I need to bind to a DropDownList. Please help.

The InstantiateIn() methode will be called when you bind the data to the grid!

yourGrid.DataBind();
