Template field is not working in 4.0?
i am implementing a update query module.i am displaying all fields from a table for a term searched. well now i am implementing update option for the record which are displayed, i have like 70 columns in my table, and i want to know how to restrict some selected fields to be only read only while the form can be updated ?Like if user select to update a record then some selected field such as "Timestamp, UID etc some selected fields" remains READ ONLY !
View 1 RepliesI 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:

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 template field in a Details View which is a dropdown selection of values.While I can get the value of the textfields in the DetailsView by using: DetailsView1.Rows(i).Cells(1).Text.ToStringI don't know how do extract a value from a dropdownlist2 contained in the DetailsView.
View 4 RepliesI 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 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'm not sure how to do this, but I did read a lot of post and searched for it.

The above javascript will close the page automatiically. My intent is to close the page after the Link in the template field is clicked, but here the page closes automatically when its loaded.
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:

View 2 RepliesI'm using a formatting expression with a template field. When the details view goes into edit mode the formatting is applied. It looks great because it applies the currency formatting. It shows up as "$60,000.00" instead of "60,000.0000". But then when I do the update it gets rejected because of the $. Is there a way to keep the formatting for the user to see in edit mode but remove the $ when doing the update so I don't get the error?
The error: Exception Details: System.FormatException: Input string was not in a correct format.

I've been struggling with trying to figure out how to do this for about 2 weeks now. I have a DetailsView with several template fields in it. The first field (Unit_Code) is a dropdownlist item where the user would select a Unit based off the Unit_Code's Unit Name. Further down I have a field named (System), system needs to get it's value from the selectedvalue or selectedindex that the user selected in the (Unit_Code) dropdownlist. I have another dropdownlist item (Component) that will need to get the selected value from System to sort on, so once I have the first Unit_Code to System figured out I should be able to figure out the System to Component part seeing as it will basically be doing the same thing.
My aspx page code is below:
