Forms Data Controls :: Add Two Controls To A Template Column At Runtime?
Feb 18, 2010
I am trying to create a datagrid with bound columns and template columns at runtime. I can successfully create the grid and columns if I only put one control per column, however, I have a need to place two controls in a single template column. If I create the column and controls at design time, it works fine as such:
[Code]....
My issue is trying to place both that label and dropdownlist into the same template column at runtime. Using code as follows, I can get one or the other successfully into the grid at runtime, but not both:
[Code]....
How can I add a second (ItemTemplate?) to that TemplateColumn? I tried:
[Code]....
but then only the dropdown list (the EditItem) shows in the grid at runtime.

I have a ASP.NET/C# web application that contains user controls with GridView controls. The GridView controls contain the following column types.
CommandField - Contains buttons like Edit, Select, Delete, ...
BoundField (x8) - Contains the data fields from the database.
TemplateField - Contains a single ASP:Menu control.
The menu control consists of the following structure.
Navigate To (Parent MenuItem)
- Location A (Child MenuItems)
- Location B
- Location C
- Location D
- Location E
What I need to do is when the OnMenuItemClick event is fired, determine which menu item was clicked (already done) and then capture what the value in the first BoundField cell is for the row that the menu item was clicked on.
So, for instance if I have three rows in the grid with the first BoundField column containing the IDs 1, 2 & 3. Then I hover my mouse over the menu on the 2nd row, and click the menu item "Location C". The "Menu1_OnMenuItemClick" event is fired and I can determine that "Location C" was clicked by e.Item.Value == "Location C".
However, how do I navigate up through the API to determine what the contents of the cell in the first bound field column are for the row that was clicked on?

I have a GridView that isn't databound until the user clicks a button...
[Code]....
The GridView has one bound column: the employee name. It also has a template field that has an empty asp:Table.
[Code]....
I populate the tblInfo in the RowDataBound event.
[Code]....
The CreateInfoTable(...) method manually creates the rows and columns for the employee. This works, and I can see my dynamically created table; however, after the user submits the form back to the server for PostBack, the rendered page after submission is missing my manually populated table. How can I save my table across PostBacks?

I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.
There is a submit button on the page as well.(this is not in a template column in the gridview)
what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.
Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.

I've an item template inside a grid which has a <asp:LinkButton/> inside it. I assign the text for the link button as
<%# Convert.ToString(Eval("Tags"))%>
Tags can have a string with multiple tags in it delimited by space. For eg. "sports", "sports cricket", "sports cricket sachin" are the examples of some possible tags.
I want to create a button for each tag inside the string. How can i create the controls (server control - linkbutton) dynamically during runtime inside the grid item template?

I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.

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?
