Forms Data Controls :: Button In GridView - OnClientClick Versus CommandName Postback
Oct 20, 2010
I have a GridView with a couple of buttons (asp:Button) in it (last row). Both of them have a CommandName attribute on them and this is handled server side in a grid_RowCommand event handler. Now, this works fine. However, I need to add client side code (Javascript/jQuery) to disable the two buttons when someone clicks on or the other. This is to prevent the user from double-clicking and creating potential havoc.
The way I have done this is by adding OnClientClick on both buttons which calls a javascript function that uses jQuery to disable the two buttons. This works fine, it's just that the page doesn't post back and so the RowCommand event handler never fires.
is it possible to stop postback Button OnClientClick()
[Code]....
[Code]....
[Code]....
so everytime it's displaying me result even if i do postback
thing is that i know i can use validator control's to validate my textbox ,but i am using some custom validations which needs to be checked before submitting of a form.
only that why i m using OnClientClick()
so i want is it possible to Control Postback it should occur only after a OnClientClick() event validationa re truel
And then I try to add some dynamic controls into the placehold control from code behind, I use the RowDataBound Event
Private Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound Dim ph As PlaceHolder = CType(e.Row.Cells(1).FindControl("PlaceHolder"), PlaceHolder)[code]....
The problem is the button CommandName is not functioning. And more strangely, if I add the button manually into the placeholder, like this: Grivdivew ItemTemplate PlaceHolder[code]....
I have a page for a product listing using a datalist control. I have customized the item template and added a link button that says Click to Order. I then databound that linkbutton with the onclientclick to the "ProductID" field, but I would like to set a variable or use some method of getting the productID of which item they clicked so I can add that product to an order. I cannot understand how to find out which item was clicked though... here is my code:
I have problems with gridview that has command button in it. The command button (when clicked) should redirect to another web page, but instead of doing it only does postback on current page.
I have a gridview with a template column that causes a postback on check changed in order to change display. It works fine:
[Code]....
And the code behind:
[Code]....
Works great, right? Well I wrote a small javascript file to make the checkboxes mutually exclusive, but now, while the post back refreshes and the javascript works, it does not show the popup extender anymore - it doesn't even enter the codebehind function.
i have a column in a gridview with an imagebutton in a column. i added an onclientclick event so that a html confirm dialog shows with ok and cancel button, so that if you click cancel, the event should not continue, but if you click ok, the gridviews onrowcommand should fire. The grid is as follows:
[Code]....
[Code]....
but when i click the button on the grid, the alert comes up and if i select ok, i get the following exception:
...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.
However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName
I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.
What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?
Call JavaScript function on GridView Row click using jQuery in ASP.Net works great!, but if I want to have a first column with an image button so the user can click only there to select a row it always produce a postback when using a button field, how can I avoid that postback while having an image button for the selection click in the gridview?
I add this code but textbox value show in empty in database .. On Button Click the GridView TextBox loose all data ..
public partial class keyexam2 : System.Web.UI.Page { //SqlConnection con = new SqlConnection(@"Data Source=.SQLEXPRESS;AttachDbFilename=D:shubhangijayonlinepaperApp_DataQUIZ.MDF;Integrated Security=True;User Instance=True"); DataTable dt = new DataTable(); //DataRow row = dt.NewRow();
Events an ItemCommand event that uses the DetailsViewCommandEventArgs event arg class which has a CommandName property.
My questions are...
What are the possible values (e.g. "Select", "Insert", etc.) for this CommandName property when operating a standard, uncustomized DetailsView control?
The "ing" events are currently being intercepted so that if the user doesn't have permission I set the e.Cancel = true and the "ed" events have redirects to send the user back to a list page that shows the items they just added/updated/deleted. However, I am not able to capture the Cancel button on the DetailsView control since there's no event for it. What I want is to redirect the user back to the list page if they click on Cancel as well.
i have a gridview with itemtemplate, edittemplate and footer template placed in update panel..i have placed Add button to insert new record in the footer template.i want partial page postback when Add button is insside gridview is clicked.
when i click the button, i'm expecting commandname to = 0, then 1, then 2, etc, as the datalist progresses, and i'm using that value in the button click's c#but i'm getting this error, i'm pretty sure i'm using this exact setup on another page and i have no problems, any idea what's going on?Server Error in '/' Application. Compilation ErrorDescription: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.Compiler Error Message: CS0117: 'System.Web.UI.Control' does not contain a definition for 'ItemIndex'
Is there a way to change the values for these two attributes on the client side and have it reflected on the server side after the postback. I tried it but it does not seem to work. I wanted to have one button on the page that I would delegate submits too, and assign these two arguments on the client side. Seems like not possible. Assuming there is a button named "cmd" in the form
I want to access linkbutton at rowcommand event which is in footer and without commandname.
Actually i have a linkbutton in empty data templates footer template. At the rowcommand name of this linkbutton i want to access other linkbutton to change its commandname.
I have a dropdown list, where when I select OPTION value a Textbox appears. The issue is that when, I submit directly the required filed errors gives me message for both ie for dropdown and Textbox. It should only give error for dropdown.
Second thing,
The textbox validation is not firing when submitted without any value in it.
I have a button for which there is a OnClientClick() event which calls a javascript method on clicking the button. Everything is good till this point.Now, when clicking on ENTER button on the key board instead of clicking on BUTTON the Java script is not being called.
I have Onclientclick event attached to the button in serverside code like below,
[Code]....
Also, the onClick event is attached for the same button in the aspx page,
[Code]....
The serverside click event should fire if the onclientclick javascript function return true. The "ValidateData()" function is called to validate the entries in the form. This code is working fine in IE. But in Firefox, both events are not firig. If I remove the line "TopPanelButton.OnClientClick =..." then onClick event is firing.
