I have a gridview containing a template field. The templated field is an image button. In code behind (page load event) I want to get the imageurl from the first imagebutton in my grid.
View 1 Replieshow to change the imageurl of an image field when I mouseover an imagebutton in a gridview? both the imagebutton and image urls are the same location.
I'm doing this in code behind but I can't seem to get the Image1.Imageurl to change to the same ImageUrl the imagebutton is pointing to.
C#
protected void ImageButton1_PreRender(object sender, EventArgs e)
{
ImageButton imageButton1 = (ImageButton)sender;
if (imageButton1 != null && string.IsNullOrEmpty(imageButton1.Attributes["onmouseover"]))
{
imageButton1.Attributes.Add("onmouseover", "Image1.ImageUrl=imageButton1.ImageUrl");
}
}
How to change Imageurl of imagebutton using javascript?
View 4 RepliesI have two webpages. Default.aspx and Default2.aspx
No code written in both pages.
I put an imagebutton without imageurl in Default2.aspx
The control is redirected to Default.aspx when Default2.aspx requests...
How does this happen?
I am having an issue with using a GridView template that contains an imagebutton control. my current ASP code is as follows:
[Code]....
I have a gridview that has a column with an imagebutton. That image button event calls my update procedure and merely updates that records status and when the gridview rebinds, the image changes and is no longer available.Whats happening is if the page is refreshed, the update occurs again. If i add this around the update code, works great the first time, but then any other updates are ignored.. is there anyway to know wether the page was refreshed vs actual imagebutton postback?
if (!IsPostBack)
{
}
Since the update is just setting a flag for that record, on another page that displays those records for a seperate department. IF by chance the first page is still open and the 2nd department resets the flag, if the first page is refreshed, that flag is reset again. so its creating some inconsistant results..
I have an image button in my gridview which I'm using to open a new window.
The code for my image button is:
[Code]....
This works fine, in that a new window is opened correctly, however, clicking the button causes a blank row to be added to the top of my grid.
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.
View 4 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.

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.
I have imagebutton in gridview and I used below code for it...
protected void Imgstatus_Click(object sender, EventArgs e) {
ImageButton Imgstatus = (GridView2.Rows[0].FindControl("Imgstatus") as ImageButton);
Imgstatus.Visible = false;
}
it just run for first row of grid view because of (GridView2.Rows[0]..I want it run for all row of gridview so instead of [0] what should I write?

I have an Image control in a ListView's ItemTemplate.
I want the ImageUrl property to say:

in place of the bold text above.
I cannot, however, get the syntax right. I keep getting "syntax is not well formed" errors.
correct syntax for this, or, if I'm barking up the wrong tree altogether, the correct method.
I've got an image URL in a gridView which retrieves the name of a file, but I need to add some text to the start and end of the value returned. This is the code so far:

The image URL renders as 'filename.png', but I need to add 'about-us/images/' before it.
At the outset i would like to welcome all as this is my first post on this forum :)probably i've got a simple problem for most of you, namly:I want to dynamically replace ImageUrl into DadaGrid cell. I've already prepare a right type of field (Image Field) and this is my code:

View 2 RepliesHaving problems with the syntax of my ImageURL inside DataList ItemTemplate want to show images that I have stored in a database.
<asp:Image ID="Image1" runat="server" ImageUrl='showimg.aspx?ImageID=<%# Eval("id") %>'/>
Makes the img syntax look like this.
<img id="DataList1_ctl00_Image1"
src="showimg.aspx?ImageID=<%# Eval("id") %>"
style="border-width:0px;" />
I'm trying to set the ImageUrl property after I've uploaded an image so that I can display the newly uploaded image, but for some reason it's not working.
If I navigate from the record I've just updated and then return back to that same record, the image then displays. It just doesn't display right after I've updated it. Basically what I'm doing is this:
Sub FormView1_OnItemUpdated(Sender As Object, e As FormViewUpdatedEventArgs)
Dim MyImage As Image
MyImage = FormView1.FindControl("Image1")
MyImage.ImageUrl = "image1.jpg"[code]....
I've left out the path intentionally because I'm pretty certain that the path I'm giving is correct... again, if I navigate away from the record and then return to it, the image displays. In addition, when I view the "Page Source" to view the resulting html, the src property of the image tag is blank . So, it's not a path issue... the issue is that its not setting the src at all which is why the image is not displaying.
