Web Forms :: Access A Template Field With Findcontrol?
Feb 28, 2010
I have this control in my paqe:
<asp:TemplateField HeaderText="Reciprocal URL" SortExpression="ReciprocalURL" ItemStyle-Width="">
<ItemTemplate >
<a href="<%#Container.DataItem("ReciprocalURL")%>" target="_blank" title='<%#Container.DataItem("ReciprocalURL")%>'>
<%#BusinessLogic.WebSite.BreakReciprocalURL(Container.DataItem("AdvLinkID"), 40)%>
</a>
</ItemTemplate>
</asp:TemplateField>
I have a select all function and I want to use an if statement to only select items if there is something in this templatefield:
Protected Sub chkSelectAll_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles chkSelectAll.CheckedChanged
For Each itm As GridViewRow In Me.gvLink.Rows
'insert if statement here to check for linkback url. if so then enable checkbox else disble checkbox to prevent user from selecting.
CType(itm.FindControl("chkSelect"), CheckBox).Checked = CType(sender, CheckBox).Checked
Next
Me.lblMsg.Text = ""
End Sub
I would do something like the above for the checkbox, but I'm not sure how to reference the control. It's a templatefield right?

My problem is as follows. I have a custom GridView control where I generate the Template fields for each column. I'm using someone elses class that extends the Itemplate and returns lables for ItemTemplate, and TextBoxes for EditTemplate.
I need this in order to implement bulk edit for the gridview where users press button Edit and all fields become textboxes, they can then change the values, and click Update button at which point I need to be able to retrieve the values from the TextBoxes in these Template Fields.
What I have tried thus far: when user clicks Edit button, my dynamic code builds the columns and specifies that the Template field is an EditTemplate, it then adds these columns to the grid view. The gridview shows the textboxes with all values retrieved from sqldatasource.
When I press the Update button, the page does a postback, as I can see Page_Load event fire, I check for a flag that I previously set when the Edit button was pressed (I store it's value in View State) and call the Update method.
In it I iterate throught the gridview rows collection, check that the RowType of each row is DataRow and call GridView.UpdateRow(i, false), passing each rows index to the UpdateRow method.At this point I have tried everything I can to find the values stored in the textboxes, but I cannot find any of the textbox controls.
I've tried using the current row's FindControl method and specifying the name of the textbox field,I've tried using Request.Params method where I can tried passing the client id, as it seen in the View Source of the page such as this
Request.Params["grid1$gvData$ctl02$MMCODE"]
Still no luck, I've tried going up an down the Row's cells, controls collections, it seem to list the counts for rows correctly, the same goes for the amount of cells for each row, but at no point was I able to actually locate any controls such as textboxes or anything else and retrieve any values from them.

I have a gridview which the columns are created programmatically.
When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
How can I add a item template in the template field I created which is binded in my datasource. Also what event handler should I use to do this.
Here's the part of my code:
[Code]....
Someone know how can I bind a label item template from the datasource. The label item template should be firstname + middlename + lastname.
If im not doing it programatically, it will be just concatenating eval(). But how can create item template and bind it programmatically?

Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

I have a Details view where I want to have a multi-select value, with the choices driven from another table.I need to iterate through the check-boxes in the list, and I do that by using a DetailsView1.FindControl("MyCheckBoxList") to find the check box list.The challenge I'm having now is that if I name the CheckBoxList differently in each of the templates (Item, Edit, Insert), then they each need a separate handler to find the control and iterate through the checkboxes. I can't find a method to fire a handler

I ran into this problem I'm sure someone else has similar encounter with, but just couldn't find a solution for it!
I want to disable few entries in the dropdownlist that's in the template field, depending on the value in BoundField when the gridview is being populated.
Below is my attempt:
[Code]....
JobStatus is the dropdownlist in the template field, and Status is the boundfield. In run time, the bolded line causes below exception: Object reference not set to an instance of an object. which I think is wingeing about null variable. Perhaps the templatefields are created after RowDataBound event?

i have a gridview that has only one column but multiple rows that i converted into a template column.
I have a linkbutton in this column that when clicked should collect the rows primary data key (forumId) and then insert it into a querystring and redirect to the threads page.
How do i select a datakey in the code behind file for the selected row without using the Selectedindexchanged event handler?

I have a gridview, whose columns I am dynamically binding. There are two fixed columns, one is a button field and another is a template field containing an image. The other columns might vary in number and behaviour, so before binding the grid, I am removing all columns of the gridview except the button field and the template field. But after doing this, if i try to do a findcontrol for the template field(Image column), it is notgetting the control. Means while removing the other columns, this image control also getting removed.Below is my code:
[Code]....
Now, after this i call the databind method. The problem is with the for loop, where I am removing the columns after the image column. And I am not able to find the control after that.In rowdatabound i am trying to find the control like this:
