View 4 RepliesI have Web page that uses LinkButton control inside Template Fields of Gridview.I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.
I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.I also tried to use OnClick Method, Session variable and Hidden variable. but when i run Response.Redirect method from Gridview_RowCommand, it clear all the Session and Hidden variable values. also tried (Response.Redirect(,false)) method but never got success.
I am generating barcode image dynamically on button click .
The image is display on the asp image control, now I want to save that image in database

using (Bitmap bitMap = new Bitmap(barCode.Length * 40, 80)) {
using (Graphics graphics = Graphics.FromImage(bitMap)) {
Font oFont = new Font("IDAutomationHC39M", 16);
PointF point = new PointF(2f, 2f);
[Code] .....
I have little strange question. I would like to Validate my Page Controls on the button click which is there in the User Control. This user control is placed on the Page. If I check Page.IsValid property on button click event, it returns false. But Validation Summary message doesn't popup. So user doesn't know what's happening. It will not save the information and it won't give the validation message too.

I have try the code that you provide in article "Dynamically Generate and Display Barcode Image in ASP.Net"It is running, however, the barcode image is not there. Eg: I put "a" in the textbox, after push the generate button, its only show "*a*" without the barcode.
The error shows that it is invalid parameter in line "Using bitMap As New Bitmap(barCode.Length * 40, 80)"Â

I have a button on click of which it will disply some records on the grid based on the value entered in a text box which is working fine, but when I enter any data for which no record is available then it should display an error message which also gets displayed but at the same time a progress bar is shown which indicates still some processing is going on even if no data is present. So , that is a big issue, can anyone please help me why the progress bar is still shown when it should stop processing after displaying the error message.

View 8 RepliesI have written a user control that captures some user input and has a Save button to save it to the DB. I use a repeater to render a number of these controls on the page - imagine a list of multiple choice questions with a Save button by each question.
I am loading the user control inside the repeater's ItemDataBound event like this (code simplified):
[code]....
The problem is that when the Save button is clicked, the page posts back, but lbnUpdate_Click is not called. The Page_Load event of the page itself is called however.
I should mention that the repeater is part of a user control, and that user control is loaded inside another user control (this is a DotNetNuke site which makes heavy use of user controls). The Save button link looks like this:
javascript:__doPostBack('dnn$ctr498$AssignmentsList$rptAssignments$ctl04$ctl00$lbnUpdate','')
how to assign the dynamicData into href={0} when user click on the Pass button?

HyperLink test = e.Item.FindControl("test") as HyperLink;
test.Text = string.Format(HttpUtility.HtmlEncode(dynamicData));
Is there a way to respond to the click event generated by any button on a form?
I am trying to carry out a response.redirect( 'button id' & ".aspx"), can it be done?
i.e. If I have a webpage called "button1.aspx" how do I get the button1.click event to trigger the redirect without implicitly coding the click event for the respective button.
i have link button at last of page when user click on link button it clicks more data.
what i want is when user reach on bottom so load more button click automatically.
I have a user control that displays some database records when I first hit the page. When I click the submit button the page load event fires again, loading the user control again. Then the button click event fires inserting a new row in the database which is not shown on the page because the user control already did its stuff. If I could get the user control to do its stuff after the button click event I could then see the newly inserted row. I can do this by pulling the code out of the button click event and sticking it in the page load event. However, I think that would be bad code flow. How can I get the user control to do its stuff after the button click event has fired?
