View 1 RepliesWith jQuery, in (document).ready I assigned a click function to all buttons of my asp.net (aspx) page. When I click a button outside , the function works properly.
When clicking a button INSIDE the form, it doesn't work. Why?

I'm using Visual Studio 2010. I tried also with jQuery 1.4.2, same problem.
I have a boolean / bit value in the database called "is_paid". Depending on this value I want to Disable a button. (the same would go for example to set a textbox not Visible, but anyway)
What I want is to Disable the button, if my boolean is 1 (true).
First I tried to convert my boolean value to text:
<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Convert.ToBoolean(Eval("is_paid")) ? "False" : "True" %>'
/>
But got an 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 ....
And my code changed to:
<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Bind("not_paid") %>'
/>
But got this error:
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:

I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
like ddl.items.insert(0,'xyz');
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.
I have this code
protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
ArrayList olist = new ArrayList() {"visible", "invisible", "visible", "visible", "visible", "invisible", "visible", "visible", "invisible"};
for (int i = 0; i <= olist.Count-1; i++) {
if (olist[i].ToString() == "visible" ) {
[Code] ....
I want to hide the button if records found "invisible".
The output must be like this:

Another question is
I want to get the button index value inside the repeater row, when the user click the button the index value display one Label3
void repbtn_Click(object sender, EventArgs e) {
Label3.Text = "The button item index that clicked in the repeater is: "; // + irepeater.Items. ;
}
i have the following code in the .aspx page
[Code]....
[Code]....
i modify the data in the text box but it is not retrived in the code behind. In code behind it always give the data which is defaultly loaded.
i can not able to get the modified data in the code behind.
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.
I used below code for above:
C#:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();
[Code]....
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.

and the LinkButton Control is

I've done things like
<%# somefunction("string") %>
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

View 1 RepliesI'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.
underline text in button how?

<asp:PanelID="pnl001"runat="server"Height="300px"Width="1174px"></asp:Panel>
How can i fix position (Left,Right,Top from panel) of that button.
i am using this code to reset all my textboxes and Dropdowmlists after the button is clicked:
void resetField(object myObj)
{
//RadioButton rl;
string temp = myObj.GetType().ToString();
switch (myObj.GetType().ToString())
{
case "System.Web.UI.WebControls.TextBox":
((TextBox)myObj).Text = "";
break;
case "System.Web.UI.WebControls.DropDownList":
((DropDownList)myObj).SelectedValue = "N/A";
break;

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..
