Forms Data Controls :: Update Gridview's Template Field - Rows Displaying "Expired" (value Less Than 0) Showing Error

Nov 4, 2010

I have a gridview and the gridview contains some boundfield, templatefield, checkbox and an update command button.

When I click the update button, I want to update only 2 columns. So I made rest of columns readonly=true.

BUT, there is a template field and I am changing the value of the template field from code behind. like below

I do not want to update the above column. so when I click update button, the rows having value more than 0 is working fine.

BUT The rows displaying "Expired" (value less than 0) showing error. It says "Object reference not set to an instance of an object."

Forms Data Controls :: Add A Item Template In The Template Field?

Sep 9, 2010

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?

Forms Data Controls :: EditItem Template Of Gridview - Template Field With Dropdown List - How To Make Current Value Sel

Dec 4, 2010

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.

Forms Data Controls :: CheckBoxList In A DetailsView Template Field

Dec 28, 2010

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

Forms Data Controls :: Formatting Template Field During RowDataBound

Mar 10, 2010

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?

Forms Data Controls :: Template Field In Gridview Not Accessible?

Jan 10, 2011

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:

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:
