remove a gridview column dynamically, removes controls in template columns
I have a interface with a treeview and a gridview. The gridview has two templatefields that handles insert/update/deletes. The gridview is handling editing of different tables so I create the other columns in the gridview dynamically as boundfields. The user selects the table to edit in the treeview.
The problem I am having happens when the user selects a table to edit the second time. The code that executes removes all bound fields, (dynamically added when user selected the first table in the treeview), but not the two template fields, and then adds boundfields specifi...
Add/Remove BoundField in Gridview with sorting on runtime throws an "column not found" exception
Hi, I am trying to allow user to see a hit count for each URL showing the gridview. Because displaying hit count is a lengthy operation, so i made it optional. The way how i made happen is by adding/removing boundfield on runtime. When i add the column, i will call a different sql script which will return an additional "count" column.
The code works fine as long as i don't sort it by "count". However, if I sort the gridview by "count" and choose to remove the column on runtime, then call the databind() method, it will throw an exception sayi...

add specific columns to the gridview at runtime
I configure the gridview's datasource at run time and set the AutoGenerateColumns property to False. How do I add the specific columns to the gridview? thanks
Try something like GridView1.Columns.Add(DataControlFieldValue).
Randy
Mr. Randy what do you mean by DataControlFieldValue? Is the name of the field in the stored proceure? thanks:)
This is the column that you want to add. It has to be of the type DataControlFieldValue. You will have to build this control yourself. Take a look at msdn.microsoft.com and search on GridView, ASP.NET, 2.0, column and you should find ...

Add new gridview controls at runtime
I've looked through a lot of posts regarding my problem and I haven't been able to find exactly what I need.I hope I can explain it well enough. I've created a gridview based on a simple one table SQL Data Source and it lists all the data just fine. One of the constraints that I'm dealing with is that the gridview is dynamic depending on what level of the organization tree they click on. The second problem is that when the user wants to edit the data, some of it is based on drop downlists and not straight text. The last problem is that I want to be able to update any field in...
Add Button Control to Gridview Column
Hi,
How do I add a button control to the Gridview column?
Upon clicking on the button, it will update the database.
I'm using Gridview for displaying or rows and Detailsview for displaying details upon selection of any rows.
What this button does is if users clicks on the button "Confirm", the code behind will update the database with a status flag and the row will disappeared from the current gridview.
I can do the row to disappeared using Databind() as once the "Confirm" button click, it will not satisfy my Gridview Select condition and it won't be there. However, I had a Select col...
Add Custom Control to GridView Column Header
I am trying to add a custom control to the column header in a grid view. I am doing this on RowDataBound, but that might be incorrect. The ultimate goal is to have the Custom Control appear next tot the HeaderText and still allow the HeaderText to sort the columns. Here is my code:1 If e.Row.RowType = DataControlRowType.Header Then
2 Dim oCell As System.Web.UI.WebControls.TableCell
3 For Each oCell In e.Row.Cells
4 Dim oHelp As New admin_controls_HelpItem
5 oHelp.ID = "hlpItem"

How to add a rating control inside a gridview column??
Anybody could help me with adding a rating control on a gridview and bound it to the data I retrieve from the database?? Thanks in advance!!
You just need a template column. Then you can bind the rating control to the integer field that represents the rating.
Here's an example of the databinding<cc1:Rating ID="Rating1" runat="server" CurrentRating='<%#Bind("Priority") %>' MaxRating="5"
StarCssClass="ratingStar" WaitingStarCssClass="savedRatingStar" FilledStarCssClass="filledRatingStar"
EmptyStarCssClass="emptyRatingStar" RatingAlign="Vertical" RatingDirection=...

How do I programatically add or remove gridView columns after DataBind?
I have constructed a dataset that includes a table populated from an IBM iSeries (AS400) midrange DB2 database using the iSeries DB2 Provider for .NET. (Yay! That in itself was a bit of a challenge!)
Now I've bound that dataset to a gridView, but I want to add a column that includes a hyperlink, and I want to remove a couple of columns.
How can I do that programatically in the code-behind?
Hi ScottDarth ,
May be you are using a GridView whose AutoGenerateColumns is set to true(which is the default). If u want to choose the columns from your dataset then u have...
Gridview control removing consecutive spaces in column output
Hi, i am using a simple GridView to retrieve data from a SQL view, and if there are consecutive spaces in the string in a particular column, something (asp?) is removing the 2nd space, and then the output has only 1 space, which is incorrect for this string. Interestingly, if I retrieve the same column with a specific select statement in a code behind file, and then output it via either response.write, or in a text box, it does the same thing. I have debugged while doing this and in the Autos window, the string is correct (with two consecutive spaces), then when it is ...
