I have a stored procedure that returns some data.However, I don't know how many columns will be returned in that procedure, but I know the names of all columns that can be returned. So what I wanted to do, is to define all possible columns in aspx page, and in server-side PrepareDataBinding method remove columns from webgrid's column collection that don't have their match in datasource datatable that I'm binding it to.</p> <p>This doesn't really work as I get an error stating that columne "XYZ" which is defined in aspx can't be found in datasource, although it was removed (I checked with debugger) in PrepareDataBinding event handler.</p> <p>I presume this then is not possible, or am I wrong? The reason I am not creating columns from codebehind is simply that I would have to check datasource for every column to see if it exists and then create that column dynamically and add it to the column collection of webgrid. We did that in old version of our application and that PrepareDataBinding method has over 1600 lines of code, so I am looking for a better way of doing this. Please help me for the love of god!</p> <p>This is my PrepareDataBinding method (column named "Check" is rowchecker column so i don't want it removed):</p> <p><br /></p> <p /><pre>Dim dt As DataTable = CType(e.DataSource, DataTable) Dim grid As WebGrid = CType(sender, WebGrid) Dim colName As String For Each col As WebGridColumn In grid.RootTable.Columns colName = col.DataMember If Not colName = "Check" AndAlso Not dt.Columns.Contains(colName) Then grid.RootTable.Columns.Remove(col) End If Next</pre> <p> </p> <p /> <p />http://www.intersoftsolutions.com/Community/Tags/remove/Tue, 10 Aug 2010 05:26:51 GMTqq397472251WebGridcolumnremove<p>how to:make "remove this column" enable in contextMenu (WebGrid )?</p> <p> </p> <p>Help me</p>http://www.intersoftsolutions.com/Community/Tags/remove/Mon, 08 Feb 2010 12:18:15 GMTlybaxAddInputSendCustomRequestFlypostBackresetclearremove<p>Hi,</p> <p>The problem is that once my custom parameters are set (using AddInput) there is no way to get rid of them... and each time my page does a FlyPostBack (using SendCustomRequest) it executes the same code (in InitializePostBack server-side event handler), because my parameters (in Request.Form) are still there.</p> <p>I'd like to clear all my custom parameters from the Request.Form during the FlyPostBack (InitializePostBack).</p> <p>1. Is there any way to clear, remove or reset my custom input values?</p> <p>grid.RemoveInput?</p> <p>2. How are custom parameters stored for such custom FlyPostBack?</p> <p>hidden input?</p> <p>3. How to modify them?</p> <p>Thanks.</p> <p> </p>
