View 1 RepliesI am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.

I have an UpdatePanel with a GridView. This GridView has a template column that is a DropDownList. The problem is that the SelectedIndexChanged event does not fire for the DropDownList. Here is the code:

I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control. Further on the content page I have an UpdatePanel control containing a GridView control and a server side button control. I have registered the button control as a trigger with the UpdatePanel control asynchronously and have set the UpdateMode of the UpdatePanel to "Conditional". I also have a "JumpLoader" control which is outside the UpdatePanel control. I have the following event for Jumploader wired up through Javascript. I am pasting the relevant sections of the code below:

I am opening a popup from aspx.cs page when a button ckicks, but at that time the source page is getting refresh.
To avoid that i want to use updatepanel, but if I use that button click event is not firing.
the code of .aspx page is
<asp:UpdatePanel ID="pnlButtons" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnPreview" />
</Triggers>

I have a checkbox, textbox and requiredfieldvalidator inside the updatepanel. Once user checks selects
checkbox I am enabling requiredfieldvalidator.
I have one more textbox, requiredfieldvalidator, validationgroup and Linkbutton outside updatepanel.
Strange thing is Checkbox checked event not firing in some cases,
1. Check the checkbox (which enables requiredfieldvalidator)
2. Click the Linkbutton (fires two validators)
3. Uncheck the checkbox (which should disable requiredfieldvalidator)
4. Click the linkbutton again (again it fires two validator, which should fire only one validator)
Note: The problem only arising when I add javascript block to linkbutton in page load event.

I havwe a Radiobutton list which i am using In the asynchoronous postback trigger of the update panel.

But when I click the button no event is firing rest all is working fine.
Button click event from inside the accordion pane is not firing. Accordion pane contains tab container inside one of its panes (5th pane) to read data from user and to save that data into database. I have used a button to save data when user click on that button. For this button i have written a click event in code behind.
this is my click event
<asp:Button
ID="Save"
runat="server"
Text="Save"
OnClick="Save_Click"/>
and code behind code
protected
void Save_Click(Object sender,
EventArgs e)
{
//my code
}
for this page AutoEventWireup="true"
have a created a dynamic solarsystem map. Basically I have a updatepanel which inside I programattically create imagebuttons of the 'planets'. These imagebuttons are given a Command event and when clicked the idea is to set the clicked planet in question as the parent and redisplay the map.Inside the command event I pass in the ID of the planet and this sets a session varible. The panel load event is then designed to use this session varible to set the new parent and display the child 'moons'
View 7 RepliesOn grid RowDataBound based on some condition i've added imagebutton dynamically. parallelly i want to add event for this button click. here is my code snippet.
protected void GV3_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TableCell cell = new TableCell();
ImageButton bttn = new ImageButton();
[Code]...
That message popup box comes, but i'm unable to catch that click event. while click on a row i want to delete that row, so want to create event dynamically. for that i've used this following dynamic click event
bttn.Click += new ImageClickEventHandler(b_Click);
private void b_Click(object sender, EventArgs e)
{
//delete record
}
but this above code also not working.

View 1 RepliesAre there any restrictions on using templatefields in gridview if the gridview is inside an updatepanel?If I click on the imagebutton, I get a exception which I can't seem to figure out.

View 1 RepliesI have a gridview which is bound to a dataset. I have placed several template fields in the grid with the following type of setup
HTML Code:
<asp:TemplateField>
<HeaderTemplate>
<asp:Label ID="Label1" runat="server" Text="File"></asp:Label>
<asp:ImageButton AlternateText="ASC" ID="imgASC" Width="10" Height="10"
ImageUrl="~/Modules/Interface/ASC.gif"
CommandArgument="eFolder ASC" runat="server" OnCommand="ImageButton_Command" />
<asp:ImageButton AlternateText="DESC" ID="imgDESC" Width="10" Height="10"
ImageUrl="~/Modules/Interface/DESC.gif"
CommandArgument="eFile DESC" runat="server" OnCommand="ImageButton_Command" />
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("eFileName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
on the code page I have mapped the OnCommand event to the following code
Code:
Protected Sub ImageButton_Command(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.CommandEventArgs)
Try
Dim img As ImageButton = CType(sender, ImageButton)
img.BorderStyle = BorderStyle.Ridge
SortOrder = e.CommandArgument
BindData()
Catch exc As Exception
ProcessModuleLoadException(Me, exc)
End Try
End Sub
My problem is that by clicking on the image button in the gridview header, the OnCommand event is not being fired. I have tried this with both OnClick and OnCommand and neither fires. I can't see what I am doing wrong if anything.
I have put my gridView inside an UpdatePanel with Timer control for auto refresh.The gridView has a linkButton column which is bounded to referenceNo column from database.
On click of this link button i want a panel to get visible. This Panel contains details corresponding to the referenceNo shown in differnt controls (mostly texboxes). Do i necessarily need to put the panel inside the Update Panel.If not how do i do it?
I have tried putting panel outside UpdatePanel, but it doesn't show panel on clicking the linkbutton nor does the values are updated inside this panel (if panel's visibility is set to true by default for testing purpose).
I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
like ddl.items.insert(0,'xyz');
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.
i have one master page and the ContentPlaceHolder that are inside UpdatePanel. I have too, buttons in master page thad feed the ContentPlaceHolder e update the UpdatePanel. When i click on any master page button, it load one UserControl inside ContentPlaceHolder. But inside one of this UserControls have a Button, that when i click on, it dont fire the click event.
MasterPage code:
[Code]....
Code that load UserControl inside ContentPlaceHolder
[Code]....
Code that contains the button that dont fire:
[Code]....
Obs: I tried sign dynamically the button, but dont works. And when i click on button, the unload method of UserControl begin called.
I have a GridView that uses custom paging inside an UpdatePanel (so that the paging and sorting of the gridview don't cause postback). The sorting works fine, but the paging doesn't. The PageIndexChanging event is never called. This is the aspx code:
<asp:UpdatePanel runat="server" ID="upSearchResults" ChildrenAsTriggers="true" UpdateMode="Always">
<ContentTemplate>
<asp:GridView ID="gvSearchResults" runat="server" AllowSorting="true" AutoGenerateColumns="false" AllowPaging="true" PageSize="10" OnDataBound="gvSearchResults_DataBound"
OnRowDataBound ="gvSearchResults_RowDataBound" OnSorting="gvSearchResults_Sorting" OnPageIndexChanging="gvSearchResults_PageIndexChanging" Width="100%" EnableSortingAndPagingCallbacks="false">
<Columns>
<asp:TemplateField HeaderText="Select" HeaderStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:HyperLink ID="lnkAdd" runat="server">Add</asp:HyperLink>
<asp:HiddenField ID="hfPersonId" runat="server" Value='<%# Eval("Id") %>'/>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="First Name" DataField="FirstName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" SortExpression="FirstName" />
<asp:BoundField HeaderText="Last Name" DataField="LastName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" SortExpression="LastName" />
<asp:TemplateField HeaderText="Phone Number" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" >
<ItemTemplate>
<asp:Label ID="lblPhone" runat="server" Text="" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
<PagerTemplate>
<table width="100%" class="pager">
<tr>
<td>
</td>
</tr>
</table>
</PagerTemplate>
</asp:GridView>
<div class="btnContainer">
<div class="btn btn-height_small btn-style_dominant">
<asp:LinkButton ID="lbtNewRecord" runat="server" OnClick="lbtNewRecord_Click"><span>Create New Record</span></asp:LinkButton>
</div>
<div class="btn btn-height_small btn-style_subtle">
<a onclick="openParticipantModal();"><span>Cancel</span></a>
</div>
</div>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="gvSearchResults" EventName="PageIndexChanging" />
<asp:AsyncPostBackTrigger ControlID="gvSearchResults" EventName="Sorting" />
</Triggers>
</asp:UpdatePanel>
In the code behind I have a SetPaging method that is called on the GridView OnDataBound event:
private void SetPaging(GridView gv)
{
GridViewRow row = gv.BottomPagerRow;
var place = row.Cells[0];
var first = new LinkButton();
first.CommandName = "Page";
first.CommandArgument = "First";
first.Text = "First";
first.ToolTip = "First Page";
if (place != null) place.Controls.Add(first);
var lbl = new Label();
lbl.Text = " ";
if (place != null) place.Controls.Add(lbl);
var prev = new LinkButton();
prev.CommandName = "Page";
prev.CommandArgument = "Prev";
prev.Text = "Prev";
prev.ToolTip = "Previous Page";
if (place != null) place.Controls.Add(prev);
var lbl2 = new Label();
lbl2.Text = " ";
if (place != null) place.Controls.Add(lbl2);
for (int i = 1; i <= gv.PageCount; i++)
{
var btn = new LinkButton();
btn.CommandName = "Page";
btn.CommandArgument = i.ToString();
if (i == gv.PageIndex + 1)
{
btn.BackColor = Color.Gray;
}
btn.Text = i.ToString();
btn.ToolTip = "Page " + i.ToString();
if (place != null) place.Controls.Add(btn);
var lbl3 = new Label();
lbl3.Text = " ";
if (place != null) place.Controls.Add(lbl3);
}
var next = new LinkButton();
next.CommandName = "Page";
next.CommandArgument = "Next";
next.Text = "Next";
next.ToolTip = "Next Page";
if (place != null) place.Controls.Add(next);
var lbl4 = new Label();
lbl4.Text = " ";
if (place != null) place.Controls.Add(lbl4);
var last = new LinkButton();
last.CommandName = "Page";
last.CommandArgument = "Last";
last.Text = "Last";
last.ToolTip = "Last Page";
if (place != null) place.Controls.Add(last);
var lbl5 = new Label();
lbl5.Text = " ";
if (place != null) place.Controls.Add(lbl5);
}
The paging works if I don't use custom paging, but I really need to use the custom paging. I can't figure out why the PageIndexChanging event isn't fired when I'm using the custom paging.
in my Site i have 3 updatepanels.In the 1 is the gridview. with templatefield in this is the imagebutton. ImageButton has commandname "Select" want to register the ImageButton as AsyncTrigger for the other Updatepanels 2 and 3
View 3 RepliesI have an imagebutton with an postbackurl and an onclientclick script. When i added the onclientclick code, if my javascript validation passes (aka returns true), the page just seems to perform a postback (the screen just seems to refresh
<asp:ImageButton ID="imgSendInfo" runat="server" SkinID="SendInfo" PostBackUrl="MyUrlOnAnotherSite" onClientClick="javascript:return onFormSubmit(this.form);return document.MM_returnValue" />
I decided to change what JS functions Im calling now since calling Multiple functions definately wasnt helping. Here's my updated code. All Im doing now is validating a single textbox and returning true or false. Even this simple function is causing the postback URL to never get called. Could it have anything to do with the fact that Im trying to call a function to return a true or false?
I am performing the search event on the button click and showing the result in datalist inside the model popup on same button simultaneous. but when i am clicking the button it vill not showing the model popup.

I am having a custom ASPX page with following structure. Its having 2 update panel and I have a ImageButton outside them. The two UpdatPanel are triggered by this ImageButton.The Problem is whenever user clicks the Imagebutton, the image in the ImageButton is getting reloaded...it disappears and the reappears. I am not able to figure out why the postback is happening when the imagebutton is place outside UpdatePanel. Is it because I am using this Imagebutton for triggering AsyncPostBack in UpdatePanel?

I have a GridView control bound to an AccessDataSource. After selecting a row I'm creating a table inside the selected row. I'm adding Buttons to this table. Their Click event never gets fired. I read about recreating the buttons and stuff, but still no luck solving the issue.
