I have a gridview which has a image button for deletion purpose in every grid row.I have placed the grid inside update panel.In IE 10(interet explorer 10) when i click on this image button it throws webpage error:
Error: Sys.WebForms.PageRequestManagerServerErrorException: Input string was not in a correct format.
and data does not delete.But in other browsers no exceptions thrown and code is working fine without any error.
CS0030: Cannot convert type 'string' to 'bool' However, if I use it one a Label it works fine: <asp:Label ID="lblIsPaid" runat="server" Text='<%# Convert.ToBoolean(Eval("is_paid")) ? "True" : "False" %>'></asp:Label>
So another trial I did was to CAST the data from the database to be the text that I want, like so:
SELECT not_paid = CASE WHEN is_paid = 0 THEN 'True' WHEN is_paid = 1 THEN 'False' END ....
System.InvalidCastException was unhandled by user code Message=Specified cast is not valid.

So I wonder, is it possible to change the "Enabled" property based on by boolean value?
I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:
In one of my Web Page, there is one Modal Pop up, in which I am using Gridview Edit, Update, CancelEdit, Delete functionality.Main functionality is : If while deleting any of the Gridview Row, if only 1 row remains in Gridview (that row can be any row), then that row should not get deleted.Rest of Edit, Update, CancelEdit functionally is working fine.
problem is: When any last row is left in Gridview, its Delete button is disables that time (as per requirement and functionality). But when user clicks on Gridview "Edit" button, update section opens, and at that time "Delete" button gets Enabled, so that time user can delete the last row of Gridview which should not be done.I had fixed this problem for "Cancel" and "Update" button of Gridview using below line:
Response.Redirect(Request.Url.AbsoluteUri); but unable to fix it for "Edit" button of Gridview. If Last row is left in Gridview , and user clicks on Gridview "Edit" button of that row, then at that time "Delete" button should not get "enabled" it should remain "disabled"
I have created a master page for website layout in my project. I have used a linkbutton control to trigger between Login/Logout functionality but when I click on this control the underlying click event handler is not being executed anyway.When I click on this control, the page pointed by its PostBackUrl property is open which should probably occure after its click event hander have been executed.
before in my asp code, calling some public function in the codebehind. But now I'm trying to do this from within a repeater item. The message I receive from the compiler is: "The name 'somefunction' does not exist in the current context." Error 97 The name 'getclass' does not exist in the current context 169
I've been working with ListView for a long time, but I haven't been using it's built-in events so far. Now I was trying and was stuck. Until I moved both LinqDataSource and ListView to another page, without a master page.
Then it worked. Same happened with GridView as well.
I do not use Update Panel. Just master page. And if I use manual methods for edit, insert, delete then it doesn't fire OnItemCommand.
Is there a known uncompatibility with databound controls and master pages? Because I couldn't find anything about it on Google.
i have tested this code and it works great separately .. the only difference is on my project i have DIV, tables, TABs and ContentPlaceHolder. not sure if this can make this code not working.. i am not getting any error..but nothing is happening.
I have a gridview which bind from a database. It populates my data which is Name, Address, Pic, PicLocation. I have a question regarding downloading the Picture/Documents that the user will upload. In my PicLocation column, it contain where the picture is located(where i saved it, like C:Pictures) from the server while in my Pic column it contain where the picture was saved inside my program location (~Pictures).
My question is how can i download the picture that was uploaded by a user? I think I can use the PicLocation here. I am using VB as my language..
