I have a gridview inside an updatepanel.After updating the gridview, accessing the individual rows does not seem to give the right row. For example:
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridViewRow row = ((e.CommandSource as Control).NamingContainer as GridViewRow);
Row from the above code gives the values from the gridview before the gridview is refreshed/updated.
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 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.
View 1 Replieshave a Gridview which repopulates itself when I click on a button outside the grid.This works fine, except that when I click on a button on the grid after repopulation, it gives the old values rather than the updated ones. I notice that querying GridView1 gives the grid when it was first populated.Anywhere I could have gone wrong?is already true.
View 5 RepliesI am working with gridview in my application. I want to get values of a particular cell in my rowcommand event on the click of a link button in a button field. Following is my code from aspx:
[Code]....
I have a GridView with an associated DataKey, which is the item ID. How do I retrieve that value inside the RowCommand event?
This seems to work, but I don't like the cast to LinkButton (what if some other command is firing the event?), and I'm not too confident about the NamingContainer bit.
LinkButton lb = (LinkButton)e.CommandSource;
GridViewRow gvr = (GridViewRow)lb.NamingContainer;
int id = (int)grid.DataKeys[gvr.RowIndex].Value;
I'm aware that I could instead pass that ID as the CommandArgument, but I chose to use DataKey to give me more flexibility.
I'm also aware that it's possible to use a hidden field for the ID, but I consider that a hack that I don't want to use.
I have one Gridview like this.
<asp:GridView runat="server" ID="gvMRLSearch" Width="100%" AutoGenerateColumns="false"
CssClass="datagrid" DataKeyNames="MRLID" >
<Columns>
<asp:BoundField DataField="MRLID" HeaderText="MRL ID" Visible="false" />
<asp:BoundField DataField="MRLCreateDate" HeaderText="MRL Create Date" />
[Code]....
But I get only the first row MRLID only, if selects the second again I get the first row MRLID.
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
}
In my grid veiw Row command sub section i used e.command argument. But it always return empty string like ""my code is like this........
Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
Dim rowindex As Integer = Convert.ToInt32(e.CommandArgument)
End Sub
I want row index to do type cast my textbox inside my grid item template.
I have a problem with my Linkbutton which is not firing the RowCommand of my gridview.
Just for an Idea what I am doing is a follows:
1. WebForm
WebForm hosts UserControl_A.
2. UserControl_A = UpdatePanel + Panels + Gridview1 + CollapsiblePanelExtender
Updatepanel of UserControl_A consists of multiple Panels.
Each Panel consists of a Gridview1.
Upon each Panel expand UserControl_B is loaded.
3. UserControl_B = Details View & a couple of Linkbuttons in GridView2
Upon clicking the Linkbutton, unexpectedly it makes a refresh for the entire UserControl_A.
But it does not fire the RowCommand of its parent GridView2.
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" />
[code]...
End Sub
asp:GridView ID="Departments" runat="server" AutoGenerateColumns="False" DataKeyNames="EntityID" DataSourceID="AccessDataSource1"
BorderColor="White" BorderWidth="0px" Height="79px" Width="232px">

<asp:BoundField DataField="EntityName" HeaderText="Department"

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)
[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 have 3level gridview. gv_parent, gv_firstslave and gv_secondslave.
how can i add gv_firstslave _RowCommand? i tried it once and as expected, i got errors.
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.
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
View 3 RepliesI have two image buttons in a gridview, one to approve the opening of the record and one to approve the closing of the record. I have added a CommandName to each button (OpenApproved and CloseApproved) and in the grids rowcommand I would like to update the database with the Username of the person clicking the button, Username goes into either the OpenLeadApprover or CloseLeadApprover field depending on which button is pressed. The grid has a sqldatasource with an Update stored procedure which has three parameters, @WorkOrderIDWhat I have tried to do in the RoeCommand event is declare a variable for the sqldatasource and add the parameter value to it, then run the update command. Here is the code:

i am using gridview for data manipulation. in gridview i have added a Edit and a delete button as a template field like
<asp:TemplateField HeaderText="Edit">
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.
[code]...
And the code of my .aspx :
[Code]....
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.
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();
}
}
