Forms Data Controls :: Mouseover On Imagebutton Inside Gridview Templatefield Triggers Server-side Events In FF?

Feb 3, 2011

In a gridview I have a TemplateField containing an imageButton defined as:

<asp:TemplateField>
<HeaderTemplate>
HeaderName
</HeaderTemplate>
<HeaderStyle HorizontalAlign="Center" />
<ItemTemplate>
<asp:ImageButton ID="imgName" ImageUrl="./img/img.png" runat="server" style="cursor: crosshair;" OnClick="imgName_Click" />
</ItemTemplate>.......

Now the odd thing at run-time is, whenever a client-side mouseover event is triggered, the app does a full postback. That happens only in firefox.

Web Forms :: ImageButton Command Event Inside A UpdatePanel

Apr 28, 2010

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'

Forms Data Controls :: Imagebutton In Datalist - Nagging For Days - Two Separate Pieces Won't Work Together

Aug 5, 2010

I'm trying to do: I have a webform with a datalist. The datalist shows projects (projectname, image and an imagebutton). When a visitor clicks the imagebutton two events should take place:

- First: data should be send to SQLdatabase (projectID, name of project, sessionID, datetime etc).

- Second: a pop up window must be opened to an existing webpage of the facilitator of the project, using an url which (is in my database).

The problem is my two seperate pieces of code-behind work fine, it's just that they won't work together. Here is my code: The imagebutton:

< asp:ImageButton ID="openButton" CssClass="openbutton" runat="server" ImageUrl="~/Images/openButton.png" CommandName="Sendto" CommandArgument='<%#Eval("ProjectID")%>' OnDataBinding="openButton_DataBinding" ></asp:ImageButton>

Code behind send to database:

protected void list_ItemCommand(object sender, DataListCommandEventArgs e)
{
if (e.CommandName.ToString() == "Sendto")
{
string projectId = e.CommandArgument.ToString();
bool succes = ProjectAccess.Projectopen(projectId);
}
}.............................

Forms Data Controls :: Refreshing Datalist In Updatepanel?

Sep 22, 2010

I have a datalist. When a user clicks a button in the datalist I change some properties and then want to refresh the datalist. However, the code below doesnt seem to refresh the datalist. Once I reload the entire page (which I dont want) the changes are visible in the datalist. I also tried setting the updatemode of the updatepanel to "Conditional" and update manually in the dlPhotos_ItemCommand, but that doesnt work either.

In bold I've marked where I want to refresh the datalist

<asp:UpdatePanel ID="upnlPhotos" runat="server">
<ContentTemplate>
<cc1:AsyncFileUpload ID="afuPhoto" runat="server" />
<asp:DataList ID="dlPhotos" DataSourceID="dsPhotos" DataKeyField="id" RepeatColumns="5" RepeatDirection="Horizontal" GridLines="None" runat="server" >
