I have an ImageButton in MasterPage and it's not firing OnClick Event.

CSS

<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/img/diary1.png"
                      style="z-index: 1; left: 315px; top: 28px;  position: absolute"
                      onclick="ImageButton1_Click" PostBackUrl="~/Default.aspx" />

related onclick event:

XML

<script runat="server">

   

    protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
    {

        Response.Redirect("Default.aspx");
    }
</script>

Even after googling a lot am not getting it done.

How do you now it is not firing?

praveen iThesisArt 29-May-13 15:24pm

There is no postback nothing.

Well your button is set to runat="server". So if there is no code on the server side, nothing will happen. Why do you have "script" tags surrounding your event handler? That code needs to be on the server.

praveen iThesisArt 29-May-13 15:36pm

Solution 1

The problem is with LinkButton.PostBackUrl Property [^].

Quote:
The PostBackUrl property allows you to perform a cross-page post using the LinkButton control. Set the PostBackUrl property to the URL of the Web page to post to when the LinkButton control is clicked. For example, specifying Page2.aspx causes the page that contains the LinkButton control to post to Page2.aspx. If you do not specify a value for the PostBackUrl property, the page posts back to itself.

You need to delete that property in order to post back to the same page.
Otherwise it will post back to the page specified in that property.

I already once tried deleting that property . Nothing at all is doing any good. If you can see both on my button click and postback i just want to go from one page to another ( ie from page1.aspx to default.aspx) nothing else .

Ideally it should work the way it is detailed in MSDN.
Please check once again. Because putting the PostBackUrl property and onclick event will not work simultaneously.

So, check it carefully, put a debugger on Page_Load and on that ImageButton1_Click event. Check whether it is going to Page_Load or not and then to ImageButton1_Click event.

Let me know what are the findings and what is the next problem. One more thing. Check the rendered html of that image button in browser and post here. I need to check that.

rendered image button in browser :
<img id="ctl00_Main_Image10" src="img/diary1.png" style="border-width:0px;z-index: 1; left: 315px; top: 28px; position: absolute" />

Here there is no onclick attribute ? And you said you have written the onclick attribute ?
Where is it ?

praveen iThesisArt 30-May-13 5:18am

Sir , I really dunno but as you can see am using the code provided earlier but its not getting properly rendered may be.. Am not sure whats wrong with the code.

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 30-May-13 5:56am

Ok. No problem. Don't worry... I am trying it at my end now.

So, you have a master page and there is a Image button inside that and you want to fire onclick event, right ? This is the requirement, right ?

Is the ImageButton inside any controls ? Now I am trying it. Please confirm about the requirement.

<asp:contentplaceholder id="Main" runat="server" >
<asp:Panel ID="Panel1" runat="server">

<asp:Image ID="Image1" runat="server" ImageUrl="~/img/headerbgq.jpg"

style="z-index: 1; left: 6px; top: 0px; position: absolute; height: 151px; width: 1332px; margin-bottom: 0px"
Width="1332px" />
<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="~/img/diary1.png"
style="z-index: 1; left: 315px; top: 28px; position: absolute"
PostBackUrl="~/Default.aspx" />
<asp:Image ID="Image3" runat="server" ImageUrl="~/img/vr.png"

style="z-index: 1; left: 246px; top: 152px; position: absolute; height: 750px; width: 19px;" />
<asp:Image ID="Image9" runat="server" ImageUrl="~/img/rcd.png"

style="z-index: 1; left: 5px; top: 150px; position: absolute; height: 166px; width: 252px" />
<asp:Image ID="Image5" runat="server" ImageUrl="~/img/hr.png"

style="z-index: 1; left: 11px; top: 140px; position: absolute; width: 1292px" />

This is code am having . So its inside asp content place holder.

Ok. I am trying the same.

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 30-May-13 6:51am

I don't what is happening at your end, but I just pasted this code, then removed the PostBackUrl attribute and added the event in code behind. It is working. I mean it is coming to the event if I debug the code.

I have uploaded the Project - http://ge.tt/5SOqY2i/v/0?c.

You can download and check how it is working.

Note- I don't have that image ~/img/diary1.png, so it will just show a faded text "Submit Query" on the Text "My Asp.NET Application" inside the header in Master Page. But it will work if you click on that. That is the ImageButton.

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 30-May-13 7:24am

Have you checked the Project I provided you ?

praveen iThesisArt 30-May-13 10:55am

Yes i did . It's working fine . Code are not getting rendered properly .

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 30-May-13 13:02pm

Which code is not rendering ?

And your problem is solved, right ?

praveen iThesisArt 31-May-13 1:15am

Nap, am still not getting it as imagebutton :(.

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 31-May-13 4:04am

Actually I don't have that image, that's why I said u that it is coming on top saying like "Submit query"... That is the ImageButton. When there is no image it comes like that only.

Ok, don't worry, I am adding any image there and uploading again. Wait.

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 31-May-13 4:15am

I have added one image for ImageButton now, You can download and check now.

Check how on clicking of that it comes to the Code behind image click function.
