i have a gridview control i added checkbox contrl dynamically but i am not getiing the reference of checkbox in button clilck event here is my code Gridvew
i would like to uncheck a checkbox in my gridview when the user clicks on that row... how do i do that in vb.
also, when trying out my website, when i do uncheck the checkboxs and click on the link to go back to the home page, the gridview on that page which links to the same table does not update the checkboxes with the new values.
I have a gridview control in which there is a column with checkbox. I will have to delete the rows of the grid selected by the checkbox. After the delete operation i am re-binding my grid we new datasource to populate latest data. The data is comig up correctly and the no of rows in the grid are also correct.
But the problem is that, if i select row 1 to delete and click on delete button, row 1 is deleted, grid is refreshed with new list, but row 2 checkbox is getting automatically checked. I don't know how this is happening. I have tried of writing code to uncheck all checkboxes after i rebind the grid. None of them are working. When i debug and see the items are actually showing as checked=false, but on the screen the check box is checked.
I am trying to delete multiple rows using a checkbox in a Gridview. When someone checks the checkbox and then click on button Delete that the rows is chosen will be deleting.

when i click on button Delete : Error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I have designed a gridview with a radio button inside the itemtemplet. I also have a confirm button. A user is allowed to check several radio button and when a confirm button is pressed then database is updated with the value of radio button.
But when i check the button it is shown as checked in UI but when I check through code behind, it shows checked property of radio button as false.
for (int i = 0; i < gvTransaction.Rows.Count; i++) { if (!((String.IsNullOrEmpty(gvTransaction.Rows[i].Cells[0].Text)) || (gvTransaction.Rows[i].Cells[0].Text == " "))) { string transactionID = gvTransaction.Rows[i].Cells[0].Text; RadioButton btn = (RadioButton)gvTransaction.Rows[i].FindControl("rbtSelect"); if (btn.Checked) { Although the radiobutton is checked code never reach here. } } }
I have a gridview were one of the colunms has a checkbox for deleting that row. When the user open the page the delete button is set to enable = false. If the user checks one box the delete imagebutton is disable = false. That works, now I need to add Javascript to enable the Delete button if the user selects checkAll, how do I do that?
I have a link button that I want to function as delete. I have to do it this way because I want confirmation before allowing deletes. In my debugger, I flagged this block of code and run it line by line. For some odd reason, it thinks my selected row. Maybe I'm overlooking something? Here's my code behind source:
i have a listview. The listview contains a usercontrol with ID="ucEquationBuilder1" which is added only! in the SelectedItemTemplate.I've came along some post which stated you can't find the control in the SelectedItemTemplate unless it is also in the the ItemTemplate.
To me this sounded ridiculous. Untill i ran some tests, and indeed i was able to find all other controls (TextBox's Labels) which where both inside the itemtemplate and the selecteditem template.
To me this is quite frustrating. Is there a way to retrieve the control which is only inside the SelectedItemTemplate without adding it to the itemtemplate?
I want to validate a GridView row only if the checkbox is selected.
My page contains a gridview and 1 button, I have used custome template for few fields in GridView. All fields are currently validated using requiredfield validator.
The validation workd fine when I click the button, but now I want custome validation, means only the rows which are selected shoud be validated.
I have a "UserDetail" table in my "JobPost.mdf". I have a "Gridview1" showing the column from "UserDetail" table,which has a primary key "UserName". This "UserName" is originally saved using Membership class function. Now I add a "Delete" linkbutton to the GridView1. This "Delete" is not autogenerate button,I dragged inside the column itemtemplate from ToolBox. The GridView1's columns now become "Delete_LinkButton"+"UserName"(within the UserDetail table)+"City"(within the UserDetail table)+"IsAdmin"(within the UserDetail table)
What I need is that by clicking this "delete_linkButton",it will ONLY delete the entire User Entity on the same row (link by the corresponding "UserName") from the "UserDetail" table,as well as delete all information from the AspNetDB.mdf (User,Membership,UserInRole,etc). I would like to fireup a user confirm,but not mandatory. At least I am trying to make it functional in the correct way.
[Code]....
When I click "delete" on the first row, I need all the record about "ken" inside the "UserDetail" table to be removed. Meanwhile, all the record about "ken" in the AspNetDB.mdf will be gone, including UserinRole table. I am new to asp.net, so I don't know how to pass the commandargument of the "Delete_LinkButton" to the code-behind file LinkButton1_Click(object sender, EventArgs e), because I need one extra parameter "UserName". My partial code is listed below:
i know how to find the index of selected row in asp gridview , but i need to find the index of selected column in asp gridview ?for ex:i have i gridview contains columns with header ( the header is the primary key i looking for ) , this grid contain linkbutton , i want to get the column header name on click on linkbutton ?
I just wrote something small up with a GridView databound to the products table of the northwind database to play around with the control. I added a template field and put a checkbox in it, ProductID, ProductName, and UnitCost. I can successfully loop through the GridView and find the rows that have the checkbox checked, and can get ProductName for each row, but keep erroring out on ProductID and UnitCost. It's probably something small, but I just cannot figure it out.Here is what I have so far:

My code behind, where I handle a button click event to get all values in rows w/ selected checkboxes:

Can I not use row.Cells[i]? The only thing Intellisense gives me that makes any sense is 'rows.Cells[i].Text'... not sure what else to do.
The page count is set to 10, when the user checks the checkbox(es), I will need to insert those records in a table. How will I know which row was selected? I found an example (untried) that is designed to loop through and insert the necessary records; but it does not address inserting records based on selecting rows via a checkbox. How do I put everything together.
I have a panel which has a repeater within it. Within the repeater I have a few controls. One of those controls is a Drop Down list which has an OnSelectedIndexChanged event. I can get this to fire without issue but I cannot find my DropDownList control within that repeater within the SelectedIndexChanged event . The repeater has an OnItemDataBound event and I can use the RepeaterItemEventArgs to find the control using e.Item.FindControl("ControlName") without issue but when that event occurs is NOT when I need to find the DropDownList.
What I want to do is have another control's Visible property be set to "true" when the value of the DropDownList meets a certain value. As far as I know I can only do this during the SelectedIndexChanged event and I can't change the signature of the event by trying to use RepeaterItemEventArgs.
