I have gone through the article "Preserving state of Checkboxes while paging in ASP.Net GridView Control", this is great one and works fine with one gridview on the page but in my case I have 2 gridviews and I am unable to preserve state of first gridview after clicking in second gridview.
I'm just wondering if anyone can assist me with this gridview problem
I have this Sql statement that outputs a gridview like this
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
* These columns are placeholders
I want to include a footer total that looks like
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
Final Total 4
Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file
So far the only tutorials I've encountered are ones the have the database bound through design view and gridviews with only one column that can be added. In my particular example I have multiple columns that need to be added and I have already bound the data to the gridview.
I'm having difficulty adding a repeating header row, every x rows, to a gridview. I'm able to add the header only once with the below code. For some reason it will only add it during the last iteration through the for/next statement. I tried manually adding three separate .addat statements to different rows and it only executed the last .addat statement. I couldn't find any information on why it's only working the one time and I hope someone has a fix or better solution.
Code snippet (Note the IsWhole() function verifies that the rownumber divided into a whole number): Protected Sub Gridview1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles Gridview.DataBound Dim grid As GridView = TryCast(sender, GridView) If grid IsNot Nothing Then Dim row As New GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal) Dim header As GridViewRow = POSTURE_RESULT.HeaderRow For i As Integer = 0 To POSTURE_RESULT.Columns.Count - 1 Dim TableCell As New TableHeaderCell() TableCell.Text = header.Cells(i).Text row.Cells.Add(TableCell) Next Dim t As Table = TryCast(grid.Controls(0), Table) If t IsNot Nothing Then For i As Integer = 0 To Gridview1.Rows.Count - 1 If IsWhole(i / 5) Then t.Rows.AddAt(i, row) End If Next End If End If End Sub
I am working with Gridview control and I am also adding radio button to each row in ASP .NET. Here is something that I would like to accomplish but I am not sure how this should done. The problem is that I have add a muliple datarow insie of the each gridview. Something like below.
So, some cases I have add a row with two rows like the example. And, the ID eventurally will be radio button where user can click.
I follow this code [URL] it works. But the example is show only for 1 row.. come to my case when user want 12 rows for the first time gridview row load. I manage to add it by using for loop. but i stuck at the how to set previous data when user add new row to 13th row. The gridview seems like refresh and the entered data is gone!
This is the exact same question as this unanswered one from May.
(edit) Note: this unanswered post exactly describes the behavior - extra scripts being added in the <head> by ScriptManager.RegisterClientScriptBlock in a usercontrol, in an UpdatePanel, is causing duplicates. C# .NET 4.0. The page is structured like this:
MasterPage Page UserControl1 (ascx) - loaded in code by Page UpdatePanel UserControl2 (ascx) - loaded in code by UserControl1
The first time the script is added as expected, in the body. The code, simply, in the UserControl2 OnInit:
I've also tried referencing "this" instead of page, which doesn't really make sense since I don't want the same script keys duplicated on the page if the usercontrol is loaded multiple times on a page, but it didn't work anyway.
After a partial postback, the script is added again - but curiously in the <head> of the page, not the body, and interestingly, lacking the normal //<![CDATA[...//]]> wrapper that asp.net usually adds.
Another script which is added by UserControl1 is duplicated exactly the same way after a partial postback.
Im into a situation, where, I need to embed linkbutton to gridview to display one field (TITLE) from database. It was done as I've added it in the itemtemplate. Now my situation is bit refined; I should add a text box and another linkbutton which should be disabled on page load and when ever I click that linkbutton which is displaying (TITLE) should make the textbox and another linkbutton visible by displaying corresponding values from the database in the textbox.
I am using the cascading dropdownlist controls from the Ajax toolkit. I have everything working perfectly and all of my select changes work. I have 3 related select boxes that all work great for single item select. What I need is for my last dropdownlist to allow for the selection of multiple items. I have tried adding the 'multiple' attribute to the final dropdown list and it allows the selection of multiple items but I cannot get the items when I post back, just a single item.
I have a page on which everything is loaded dynamically.
There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event. The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:
I have a GridView that refreshes based on user input. The GridView is setup to display data in pages if the number of rows is more than 20.Here is a scenario that I need resolved:When the user selects an item the GridView displays 2 pages of data. The user selects page 2 to view its contents. Next the user selects another item that also has 2 pages. By default the GridView remains of page 2 when it is refreshed with new data. How do I ensure that the GridView defaults to Page 1 when the user clicks on another item? The GridView is databound to the control that the user selects.
SourceForm.aspx contains a databound gridview which I have added a checkbox column for multiple row selection. OnClick of a button I want to display any selected rows on another page, Target.aspxSo far I have successfully captured textbox input properites using PostBackUrl between the two, e.g.
SourcePage.aspx <div> Enter your name: <asp:TextBox ID="_nameTextBox" runat="server" /><br /> Enter your age: <asp:TextBox ID="_ageTextBox" runat="server" /><br /> <asp:CheckBox ID="_marriedCheckBox" runat="server" Text="Married?" /><br /> <asp:Button ID="_nextPageButton"

Some examples I've tried to follow point towards using DataKey Rows of chkSelected
I have a simple user control which contains a textbox and a dropdownlist. I need to add this control multiple times to my page then save the details to my db, validating each control. When they re-enter my page I need to load the user control for each record in the db populated with the data they entered. They can then edit the data, delete the row or add new rows.
I'm trying to find the cleanest most efficient way to accomplish this. I realise I would need to re-add the user controls after each postback re-populating the data. Would the best way be to add each row to an arraylist or list of type object, save it to the viewstate and re-add the controls with data on postback, or is there another method which would suit?

I'm looking to add controls dynamically to a table across multiple functions. I'm trying to convert this from a C# app to a web app using asp.net, though this is my first time using asp.net with no web development background. I read the creating tables dynamically in the FAQ but I'm still not sure how to do this.
When pressing the submit button on my form, it will create a table in a place holder. Eventually I would like it to generate urls based on the users input and do this in a function other then the one I created my table in.
In my C# app I was able to add text to a listbox using: lstOutput.Items.Add("Text"); across multiple functions but I'm having trouble doing this with a table.
I understand that my table is a local variable in the submitButton_Click function, but how do I make it global to add rows, cells and controls to it in other functions?
As you said that for storing use data table and make property in the .ascx.cs file but I have problem that I m not able to get that property in the .aspx page. How to add multiple instances of web usercontrol on page on button click event?
I have an inventory page with a gridview that shows 1 item per record, each item starts with a checkbox in the gridview. Currently users can select multiple records and hit the order button and everything has worked well. Now I have multiple pages in my gridview, and if a user selects a few records from the first page, and then goes to the second page, all the records (checked checkboxes) disappear from the first page.
I create reports sometimes with a gridview and export the data to excel. Lets say I have like multiple gridviews and I wanted to export each gridview to excel under its own spreadsheet.
So gridview1, gridview2, gridview3 are exported to excel under $heet1, $heet2, $heet3.
I know how to export multiple gridviews to 1 excel sheet but I don't know how to export them separately under their own spreadsheet.
I've been researching online, and i'm continously searching, but does anyone know how to do what i'm trying to do with the gridview and excel or is this not possible?
