Forms Data Controls :: Find Complete Row In Rowcommand In Gridview?
Nov 29, 2010
In my database table I have ID,FirstName,LastName,Address fields.I have bound the FirstName,LastName in Gridview with Eval Method.But have not bound the address coz I m not dispalying address.Now there are textboxes below the gridview which gets filled when I click the edit button in gridview with values in the gridvoew row.I am getting the FirstName and LastName (using find control in rowcommand) but not the address.How can I get the address
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 }
GridViewRow row = (GridViewRow)(((Repeater)e.CommandSource).NamingContainer); Repeater _rpt1 = row.Cells[8].FindControl("rptReg") as Repeater;

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.
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)
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'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.
I have gridview+sqldatasource. In gridview i have button DELETE. But i want on click this button for some rows execute DELETE command other rows UPDATE. I did:
[Code]....
@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.
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
[Code]....
- the aspx.vb
[Code]....
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.
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.
I have a gridview with Action button. When this button is clicked Javascript Confirm Popup will Display, after click on OK the Event have to fire GridviewRowCommand but the strange thing is: when the button is clicked, the rowcommand method is NOT fired! When I place the code on a separate page the event is fired, but when placed inside the tabcontainer for some reason it isnt...
I have a gridview with a button. When the button is clicked another gridview should show up showing some details of the clicked row.The strange thing is: when the button is clicked, the rowcommand method is NOT fired!

I have a gridview with a ButtonField. When I leave the button type as the default LinkButton, clicking that button fires the RowCommand and everything works as expected. As soon as I change the button type to ImageButton and assign an ImageUrl, clicking that button does not fire the RowCommand.
I already implemented the dynamic templatefield which will re-created in every postback. Everytime I make a postback in the page I see no problem but when I click my imagebutton inside the gridview then the dynamic templatefield disappear.
To double check if it is really gone at all I just select the second page of the gridview using my customize paging using dropdownlist outside the gridview and the templatefield with its correct data reappear again.
I already put a variable inside the rowcommand to see if the number of columns are the same with the number of columns the gridview render together with the dynamic templatefield during debugging and it is there but cannot render that templatefield in the client.
I'm trying to retreive values entered by users in the textboxes in the footer of the gridview and insert these values into another sql table.My code is as follows :-
protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e) { if(e.CommandName.Equals("addnew")) { TextBox t1 = (TextBox)GridView2.FooterRow.FindControl("tfrm"); string frm = t1.Text; TextBox t2 = (TextBox)GridView2.FooterRow.FindControl("tsub"); string sub = t2.Text; string cmd = "insert into suggestions values('" + frm + "','" + sub + "','c','c')"; con.Open(); SqlCommand com = new SqlCommand(cmd,con); int a = com.ExecuteNonQuery(); GridView2.DataBind(); con.Close(); } }
But the strings 'frm' and 'sub' returns null values.
I am tryting to reach controls in the gridview rows by RowCommand event. I can take values of controls which are binded to gridview source successfully . But for all other controls which is not binded to gridview returns NULL value. All controls run at server. Why is that?
I have a GridView attached to an ObjectDataSource (returning a DataTable) in a UserControl. The code is really simple. Data comes down fine when the page is first rendered. When I click on Select or Delete (inside TemplateFields), RowCommand is supposed to fire but it doesn't, the page goes straight to Page_Load. I literally have 0 other event handlers that are set on this control and everything else in the codebehind shouldn't even fire if it's a postback. Also on postback, the Select and Delete buttons disappear. It looks like the TemplateFields are still there but they're empty. The data fields (all of two columns) post back fine.
I have followed your Nested level gridview and found it working, but i want add a button in the child element(from your example i will have a btn in Product grid and it should get contact_id (parent datakey value as well) ),as i need to update in database.
