Web Forms :: Programmatically Fire Treeview Selectednode Changed From Gridview Rowcommand Event
May 27, 2010
I have a treeview on the left panel and the gridview in the content page. Both the treeview and the gridview bind to the same datasource and have the same functionality. For instance, clicking employer in the treeview and clicking the employer link in the gridview take you to the same page. All I want is when I click the employer link in the gridview, I want the gridview row command event to call the selectednodechanged event of the treeview, so that the treenode for employer has the selected node style and performs the function of hte selectednodechanged. i have tried treeview.nodes[0].select but this does not fire the selectednodechanged event.
I am creating custom Gridview for dynamic Columns (getting columns from Database) and addting textboxes to headers for filtering data. I set the "EnableViewstate=False".
My problem is when I click on Filter Button it is not firing RowCommand event.
I am using a dropdownlist in my application and it has corresponding SelectedIndexChanged() event.I would like to invoke GridViewEdit Event when SelectedIndexChanged event fires from dropdown list.Is it possible to implement this...??
<asp:DropDownList ID="ddlStatus" Visible="true" AutoPostBack="true" OnSelectedIndexChanged="ddlStatus_SelectedIndexChanged" runat="server"> </asp:DropDownList> protected void ddlStatus_SelectedIndexChanged(object sender, EventArgs e) { //Code to fire the GridViewEdit Event to put a row in edit mode }
I want to take the treeview's selectednode and then search control from the database for that particular node and then bind it in gridview column dynamically.
The problem is like i am not able to get treeviews selected node in OnInit method and if If i bind it in page load or anyother i am able to get treeview selected node but i cant create dynamic columns at that time using template handler.
How can i get the treeviews selected node or what is the option to bind usercontrol in gridview column dynamically without template handler.
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 don't want to use Sessions to handle each click event inside treeview selected node changed.Secondly, if you suggest me to use treenode.SelectedValue then I would say my values are dyanmically generated.Everytime a node a clicked, the selected node value is sent in the next request xml to get response and xml schema is different for each click. How do I handle this each click event other than using session variables. I thought of using Request.Item (and integrating with URL redirect property) but I don't want to use that.
I have an aspx page in which the code-behind is in VB.Net. I have a TextBox field on my page. In the code-behind, the only event that I have for this field is the TextChanged Event. However, whenever I enter data into the TextBox field, the event won't fire. What would prevent this from happening?
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've done my research about how will i save the selectednode in treeview and scrollbar state after page navigation but i can't find any solution. Is there a way or alternative way on how to do this?
I have an asp.net page with a list box on it. Multiple event handlers subscribe to its OnSelectedIndexChanged event.
When I change the SelectedIndex programmatically none of the events get fired.
Now a hack for this is to call each event handler, but this has already caused bugs since people didn't know they had to do this when adding a new event handler.
I can do this in a Winforms app and even when SelectedIndex is changed in code the events fire.
I'm trying to manually create a button and add a Click event handler for it in code. However when the button is clicked the event handler doesn't seem to react on event (or event isn't called).
we tested the code in Visual Studio 2008 and everything worked just as it should. And I'm using Visual Web Developer 2005 XE. So I assume that I'm missing something to be done manually being in VWD 2005 XE, or the problem is in VWD 2005 XE it self.
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'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.
The AsyncFileUpload control turns green, indicating that the attachment was successfully uploaded, but the designated method for handling the server side UploadedComplete event is never executed.
Elsewhere in the page, some JavaScript opens a popup. When the popup is filled out and submitted, I want to use JavaScript to fire that OnSelectedIndexChanged event in the opener page. I found some other code that does something similar:
if (window.opener != null ) { var cf = window.opener.document.forms['aspnetForm']; if (!cf) { cf = window.opener.document.aspnetForm; [code]...
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.
