VS 2008 / Confirmation Message Before Deleting In Grid?
Jun 21, 2011
i'm using this code;
Code:
Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
Dim l As LinkButton = DirectCast(e.Row.FindControl("LinkButton1"), LinkButton)
l.Attributes.Add("onclick", "javascript:return " & "confirm('Are you sure you want to delete this record " & DataBinder.Eval(e.Row.DataItem, "CategoryID") & "')")
End If
End Sub
but i still encounter these errors:
Object reference not set to an instance of an object.

I want to add a confirmation before deleting the data and popup message box...
I want to confirm from the user before deleting a record. I want to show a message box to confirm operation... How I do that.. I used query to delete a record on button's click event..
Does anyone know how to program a Confirmation box to pop up when deleting a row in a ListView Control in ASP 3.5 in VB? I have the delete buttons in both the ItemTemplate and AlternatingItemTemplate.
I put the code above to display a confirmation message box.. but the problem is whatever button i clicked, it still continue.. all i want to happen is when i clicked the cancel button, it will not proceed..
I have one page which contains 3 panels and 3 buttons. Each panel connects one button. When one button clicks, the relative panel appears and other panels are divisible. For each panel, I design a textbox, a merge button and a gridview. When user input information into the textbox, the gridview shows the detail data from the database and two checkboxes. The next step, user uses checkboxes to choose two different rows of data and click the merge button. I need to show a confirmation message based on the selection user made i.e. Are you you want to merge A to B.
write the code to show the confirmation message which is works perfectly in Page_Load() method. But the problem is the page contains 3 panels. Do I need to write code for each panel to show the confirmation message and put 3 sets of the code in Page_Load?
I need to dispaly a message box for confirmation to delete an Item or not but not sure how to do that if I use javascript alert, than how will I get confirmation?
I have a button in my gridview recurring through the rows which requires confirmation before it deletes a record. Instead of it asking, "are you certain you want to delete this contact?" I want it to specifically ask the user, "are you sure you want to delete <the name of the contact>?" This is the button that I have at the moment and I have no idea how to place the contact's name in there:
I have almost completed a competition entry form however i now find myself stumbling over a label which is to display a confirmation message that the entry has been received.
Stepping through the code using debug/breakpoints shows that the code is running the cycle but the end result of the form is just blank fields.
Here we have a function The 'ConfirmDelete()' which is executed each time a click event occurs on the page.
2. Then we use a logic that to find which element was clicked on i.s we append a word 'DELETE' to the ID of the control.
3.And finally check if the clicked element having ID is 'DELETED' , then the javascript function will be execute to ask the user about his/her confirmation.
I am using Local reports(RDLC) for my reports in Asp.net
I have the following code in my button.I am able to send my pdf report as mail,and every thing is ok,But Problem is I am unable to produce a Confirmation message,like "Mail sent successfully".How could i change my code.
when trying to translate the confirmation message to Norwegian i get the following error: Cannot have more than one binding on property 'OnClientClick' on 'System.Web.UI.WebControls.LinkButton'. Ensure that this property is not bound through an implicit expression, for example, using meta:resourcekey. i use Explicit localization in the following manner:
<data name="lnkMarkInvoicedResource.OnClientClick" xml:space="preserve"> <value>return confirm('Er du sikker?');</value>
if i remove the meta attribute i get the English text(default). how do i get the Norwegian text appearing without resorting to using the code behind? Update: removing the meta attribute prevents the exception from occurring but the original problem still exists. I can't get the Norwegian text to show. only the default English text shows.
Another Update: I know this question is getting old but i still can't get the Norwegian text to display.
I want to include a confirmation message upon check out of my websore. I have already included it in the load statement and the message box appears as intended. I still don't know how to obtain the value (true or false) so that I can continue with check out or return to page. I've been reading a lot about using scripts, but all the scripts that I've seen are in the main aspx page and not the code behind page. I'm using VB2010. give me an example of using code behind page in VB to filter the result of the confirmation box?
On a check box check changed I want to test some conditions and based on that I want to display a confirmation message. Based on the user action, OK or Cancel I want to proceed or stop the process. How can I do that. I tried this,
[Code]....
Even I click Cancel the rest of the code also executed. How can I handle this?
I have the following situation I am having trouble with.
1) Users select some items from a checkbox & type a message in a textbox
2) The user clicks on a message preview button
3) Based on what they had selected, a message will be created. This message is stored in a database
4) I am using showModalDialog to display their message to the user.
5) The user is given two options, send & cancel
**Here is where the problem starts**
6) If the user clicks send, I want to call a server side method that sends this message to a portal (method already developed) I was trying to use "__doPostBack....", but this is throwing a javascript error.
When the user clicks the submit button on a form I want to return a success / failure message to the user and i'm wondering what the best way to send the message back to the user is.
For example on a login form if the user enters an incorrect password i'd want the view to reload with a message telling them that login failed. Or on an update form the original view they had would show up with a message saying update was successful.
My idea is to have a few partial views or HTML helpers that look for a ViewBag property like "ErrorMessage" or "SuccessMessage" and conditionally show themselves when these properties have a value. These components could be added to the _Layout or manually each form where they are required.
Edit
I have since found out that the ValidationSummary method takes a parameter of whether to exclude property errors which means you can use it to show when login / registration has failed. But there seems to be a bug where the validation summary is still generated even if there are no errors.
