I was putting all my editing code in my RowCommand event method. This works fine for everything except "update". I am not receiving a row index. I am getting one for "delete" and that works fine, but none for "Update"
[Code]....
[Code]....
When "btnEdit" is clicked, "RowCommand" event is raised where I want to the catch row index of the row which was set to Edit mode.The Reason for doing this is ......I am using paging with page size = 4. When I click the fourth row (suppose), page is postedback and then the user has to scrolldown to get to the edit row
I am getting error as Procedure 'storedproc2' expects parameter '@NewMessage', which was not supplied.Basically in this I am taking the text in one cell and add sometext to it and update in the next cell of the row.
My .aspx contains
<asp:SqlDataSource ID="mySource1" runat="server" ConnectionString="<%$ myConn %>"
SelectCommand="storedproc1" SelectCommandType="StoredProcedure"
UpdateCommand="storedproc2" UpdateCommandType="StoredProcedure">
<SelectParameters>
<asp:SessionParameter Name="AcctId" SessionField="AcctId" />
</SelectParameters>
<UpdateParameters>
<asp:SessionParameter Name="AcctId" SessionField="AcctId" />
<asp:SessionParameter Name="Id" SessionField="Id" />

I have two gridviews tied to a SQL backend both being displayed within an update panel. Both the gridviews have a linkbutton connected to a rowcommand. When clicking on one of the rowcommand link buttons, the database is updated and the update panel is refreshed (moving the record to be displayed in the other gridview in the panel). However, when the rowcommand from the other gridview is clicked, the code is run and the database is updated, but the update panel is NOT refreshed.I have debugged it and have found that the code is running as expected. It fires off the function and updates the database. If I click away from the page and then go back, it does show the data in the proper gridviews, so I know that the code is working.
View 3 RepliesI have a gridview where I am opening a popup page when user selects a row. If I am not using update panel then Select button is able to open popup page.
If I am adding Update panel, the popup page is unable to open. What could be the cause?

using vb.net/asp.net 2005 and SQL Server 2005.I had similar issue yesterday: I created a unique index on a table to prevent duplicates when user tries to edit existing records in a gridview.This works fine and I am seeing the "cannot insert duplicate key row message...." however I need to catch the exception because I do not want to display the table and column names.I have this set up but its not catching the exception, the exception is displaying but not my version, does anyone know in what gridview event and how I can catch and customize this exception? what i have now (but not working ) is:

I have a gridview based on two dropdown lists. The first list limits the values of the second dropdown list. On page load all available results are inserted into the gridview. After selection of the dropdown list, the gridview is refreshed with data limited to the two selections. This will result in 200 rows of available data. The user can select the page they want to go to using the page index.
They will then select the row to edit. Everything is fine up to here. Then the user will update the record with the appropriate data from the dropdown lists in the gridview or update the text box as necessary. They hit the update selection and the row is updated. The only problem is that they are brought back to the first page in the index. Since most of these people will be working through the list relatively in order, it would be nice if they could stay on the page they were working on rather than going back to the beginning every time. Is there a way to go back to the same pageindex they were at when they started the update?
I am including my code. I tried to use a variable for the pageindex as well as the selected values of the dropdown lists but I am quite sure I have applied them in the wrong places.

I have several Gridviews that display data from the same table. They are separate for visual effect (Different characteristics). If I select on an item from any grid they can all execute the same code (Show Details).I'm using a row command GridViewCommandEventArgs.Is it possible/How can you get the gridview name from the row command so that I can use just one subroutine.
Sub GV_RowCommand(ByVal sender
As
Object, ByVal e
As GridViewCommandEventArgs)
If e.CommandName = "select" Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim row As GridViewRow = ????.Rows(index)
I have a gridview with a button column that triggers the following code:
[Code]....
My gridview has multiple rows and multiple columns, yet I do not get a return on my Response.Write.Is there any obvious problem with my code here?
I have one button and gridview.
The button is located at the outside of gridview.
By clicking the button, I want to trigger the RowCommand event in that grid.
Obviously, I know that I can create same function to run it in that button to achieve samething in the RowCommand event.
However, I would like to know that techinically, I can simply trigger the RowCommand event from outside of GridView.
I have a usercontrol that has a gridview. I have a few boundcolumns and then a buttonfield. The buttonfield needs to have a confirm message box and then proceed to the RowCommand event. In the RowCommand, I'm trapping for a CommandName called "DeleteFile".
The weird thing is everything works correctly with deleting a row if the onclick code is not registered. I'm using attributes.add for this.
I know there is another option for using a templatefield and then a button rather than a buttonfield. But, I've noticed that this approach causes a postback that effects another usercontrol on my page. It thinks I've submitted it which can either cause it to error out or potentially sumbit more information which I want to avoid.

I'm trying to fire the RowCommand event on a DataGrid control. I've previously done that, but not in this precise case.
Actually I'm working on someone else code so I can't really change the structure of his page excepted if it's really necessary.
The code of the page is heavy, so I've summarized the problem in a small project and the page behaves the same way too.
Basically I have a GridView which I bind to a DataSet. According to those data, I sometimes need to add, at the end of a row, a "Details" button (a LinkButton).
By pushing this button, I want to show a second GridView containing those details.
Let's add to this that the columns number of the first GridView is variable, those LinkButton need to be added dynamically.
The first GridView is generated without any problem and when my mouse is over one of the LinkButton, I can see that the link is something like "javascript:__doPostBack('dataGridView$ctl02$lnkDetail','')". When I click on this link and debug step by step : Page_Init, Page_Load, OnPrerender, RowDataBound but no RowCommand, and I don't know why!
In the exemple, I've explicitly set the EnableViewState to true from what I've read here and there, but nothing's changed.

@index - DeleteParametrs in sqldatasource.
But DELETE works and DELETEVIRTUAL doesn't. Then i insert sourceMain.Delete() in rowcommand after sourceMain.DeleteCommand ... But it's doesn't help me.
I am trying to access column value by using DataBinder.Eval on RowCommand event of Gridview. It always return NOT SET TO ANY INSTANCE error for eveytime. I know how to do this by employing a label control in ItemTemplate, but am trying to find a way to bypass.

It has to do with the RowCommand 'Cancel'. When clicking on my Edit button for a row, the GridView puts the row into edit mode without a problem (I have no code for the Edit command, I let the control do everything).
Once in Edit mode, if I click the Cancel button (again, I have no code handline this RowCommand, I let the control handle it (like i do with many other GridViews)) I get the following exception:
"System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I'm having a hard time figuring this one out, i got a gridview with a sqldatasource that is loading its content, to custom columns a ButtonField and a Boundfield, both are loading in page load event,When i click the ButtonField its trigerring the rowcommand event but i can't figure out how to read the value of the cells wich i need to get for the next step of the program.Here what i got so far :- The aspx

I'm getting the correct index and command name but i cant get the button value or bound field value either.
i am using a grid view . i have added a linkbutton in cell[0]. when clicking on this butoon the below event is working.. actually i tried to get the cell[1].text... but not getting any cell values except cell[0].text... get the cell[1].text value.
protected void grvSchedule_RowCommand(object sender,
GridViewCommandEventArgs e)
{ if (Convert.ToInt32(e.CommandArgument) == 1)
{LinkButton lbt = (LinkButton)e.CommandSource;
GridViewRow grvRow = (GridViewRow)((DataControlFieldCell)lbt.Parent).Parent;
txtTime.Text = grvRow.Cells[0].Text;
//txtTime.Text = grvRow.Cells[1].Text;
mvwApp.ActiveViewIndex = 1;
FillToSavePage();
hfdConsId.Value = ddlConsultant.SelectedValue.Trim();
}
}
i tried something like this but did not work:
GridViewRow row = (GridViewRow)(((Repeater)e.CommandSource).NamingContainer);
Repeater _rpt1 = row.Cells[8].FindControl("rptReg") as Repeater;
error:
Unable to cast object of type 'System.Web.UI.WebControls.Button' to type 'System.Web.UI.WebControls.Repeater'.
is there a way i can have the below code in `OnRowCommand` event using GridView?
actually i am trying to delete the row from the gridview control and when the user click on it and i am grabbing the mulitple ids and passing to SP and update the table and `databind the gridview`
GridViewRow row = gv.SelectedRow;
Repeater _rpt = gv.Rows[e.RowIndex].Cells[8].FindControl("rptReg") as Repeater;
Repeater _rpt1 = gv.Rows[e.RowIndex].Cells[9].FindControl("rptVisitor") as Repeater;
foreach (RepeaterItem item in _rpt.Items)
{
TextBox _txt = item.FindControl("txtId") as TextBox;
TextBox _txt1 = item.FindControl("txtName") as TextBox;
//update db
