I have set the Datasource of my gridview in code behind and created no columns (All columns in gridview are created automatically). Then I added a template column in gridview. Now I want to change the order of my Templated column in gridview at runtime. I want to show the templatedcolumn at column 20 but it is shown as first column. My Grdiview looks like this:

my c# web app containing a gridview template field with one column as dropdownlist,drop down list contains 3 items such as disposed,fitted to,battery room,when i click edit button corresponding row is selcted bt dropdown list contain its first value ie disposed instead of actual values in database, i used the following code for retrieving values from dropdown during updation
i want to sort my Gridview rows by a template column that is not bound to any database field. This template coulmn just has a label whose text i set in code depending on a value in a different column that is databound. So am stuck on how to set its sortExpression since its not linked to an column.
1) How to add new row in gridview below the selected row.
2) how to change gridview row data by changing the dropdown value in template column. e.g) i have a gridview which shows the id, desc, qty etc. and there is template field of dropdown which shows the id.
now i want to do 2 things.
i) when i click on new row button a new row should be added (at desired location will be preferred)
ii) when i change the ID from dropdown field the entire row data should change according to new ID.
I have a ASP.NET/C# web application that contains user controls with GridView controls. The GridView controls contain the following column types.
CommandField - Contains buttons like Edit, Select, Delete, ... BoundField (x8) - Contains the data fields from the database. TemplateField - Contains a single ASP:Menu control.
The menu control consists of the following structure.
Navigate To (Parent MenuItem) - Location A (Child MenuItems) - Location B - Location C - Location D - Location E
What I need to do is when the OnMenuItemClick event is fired, determine which menu item was clicked (already done) and then capture what the value in the first BoundField cell is for the row that the menu item was clicked on.
So, for instance if I have three rows in the grid with the first BoundField column containing the IDs 1, 2 & 3. Then I hover my mouse over the menu on the 2nd row, and click the menu item "Location C". The "Menu1_OnMenuItemClick" event is fired and I can determine that "Location C" was clicked by e.Item.Value == "Location C".
However, how do I navigate up through the API to determine what the contents of the cell in the first bound field column are for the row that was clicked on?
I created one template column dynamically(on button1 click event) on gridview. also i am adding one linkbutton dynamically on rowdatabound event of gridview. when button1 clicked gridview displays properly with linkbutton. when i click on linkbutton, then all linkbuttons disappears blank column displays. in that linkbutton click i am doing the session expiry check if not then response.redirect to another page. why that template column's link button disappears ?
I need to add a checkbox as item template column in the grid view, however i am successfully adding the control as first column to the gridview,but i need to add the same as a last column in gridview through source and not mostly programatically..
I've defined template column in gridview containing checkbox as first column and some number of bound columns. I use Datacontrolfieldcolletion class to clone the columns and arranging columns of gridview at runtime a-bound column (not template column) then after first postback template becomes invisible. It doesn't matter what template column contains (button, checkbox, ..). I've check that gridview doesn't have this problem. how to manitain the state of the object of datacontrolfieldcolletion class which is used for arrangeing columns
I have a GridView that isn't databound until the user clicks a button...
The GridView has one bound column: the employee name. It also has a template field that has an empty asp:Table.
I populate the tblInfo in the RowDataBound event.
The CreateInfoTable(...) method manually creates the rows and columns for the employee. This works, and I can see my dynamically created table; however, after the user submits the form back to the server for PostBack, the rendered page after submission is missing my manually populated table. How can I save my table across PostBacks?
I am having a problem in adding template colum with textbox at runtime, when i click on button it wont add the column but when i press it again for ading second column then it add the first column to the gridview..
here is my code on button click event...
DataTable dtSizeDiscount = ((DataTable)(Session["SizeDiscount"])); DataColumn dc = new DataColumn(); dc.ColumnName = "$" + txtSize.Text; dc.DefaultValue = "0"; dtSizeDiscount.Columns.Add(dc);.......
like this in a function in AddColumns button clickevent
gv.Columns.Clear() Dim chkCol As New TemplateField chkCol.ItemStyle.Width = 20 chkCol.ItemStyle.HorizontalAlign = HorizontalAlign.Center gv.Columns.Add(chkCol)
and in row databound event i added checkbox control to this template field. like this
Protected Sub gv_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then Dim chkbox As New CheckBox chkbox.ID = "chkSelect" e.Row.Cells(0).Controls.Add(chkbox) End If End Sub
HERE I WANT TO GET CHEKC BOX IN btnok click event
Protected Sub btnOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnOk.Click Dim linkId As String Dim summary As String = "" 'Enumerate the GridViewRows For index As Integer = 0 To Me.gv.Rows.Count - 1 'Programmatically access the CheckBox from the TemplateField Dim cb As CheckBox = CType(gv.Rows(index).Cells(0).FindControl("chkSelect"), CheckBox) If cb IsNot Nothing Then If cb.Checked Then linkId = Me.gv.DataKeys(index).Value End If End If Next Me.Page.Title = linkId End Sub
But here i am not getting Check box even i used find control. how i get checkbox
I have dropdown list in a DetailsView edit template. It works OK, except when I edit a row, the dropdown list does not initialize to the existing value that shows in the textbox that displays in the item template.
I tried to initialize the selected value of the dropdown list with some lines of code like this but with no effect...
I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.
There is a submit button on the page as well.(this is not in a template column in the gridview)
what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.
Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.
Here is what I am trying to do.I have a drop down list along with a 'Add' button (which are always visible). There are some other 'Label', 'TextBox', 'Button' in the page (which is not visible on load). Depending on the user selection from the first dropdown (and when click on 'Add' button), I would like to dynamically set some of the Controls visible.
For example (as per below code): When User selects 'Email' ... Label3, TextBox3 and Button3 will be visible. Again when user will click Button3, all controls will be invisible. I was able to Show and Hide those controls as per user selection and button click.
What I would like to do is, rearrange the controls. For example, If user selects 'Email' and click 'Add' button (Button5), It would display 'Label3', 'TextBox3', 'Button3'. Then if user selects 'Name' from the dropdown and click 'Add' button again, it would display 'Label1', 'TextBox1', 'Button1' below the Email controls. As of now it is apperaing on sequence as listed in html (Name controls always come first when visible, then 'Phone', then 'Email'). I would like to display the controls as sequesnce as user selects.
And next is when we will click the Button3 (which will hide the email controls), All other controls below email controls should rearrange and come up.
I hope I was able to explain what I want to do. There might be a very easy way (may be there is already a toolkit I don't know about).
I have a gridview in which one of the columns is displaying an ID. I have another column which is a template column where I am showing a flash bar graph. How can I get the ID displayed in the ID column to come up in the template column so I can link the bar graph to the corresponding data in mysql using the ID?
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
i have following code to bind gridview with sql datasource
if it is 0 it checked it(checkbox) otherwise not ,all are enable too, i want that if it is checked it should become disable ,secondly i write some lines in code behind like row_databound event and put certain break point but it does not stop over that break point.
