I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:

I have 2 gridviews they are bind by sqldatasource ,it contains Id , Name and Price
i dont want to show ID coloumn when page is loaded.How to hide it?
Suppose I have a e-shop web app. I have a product categories table in my database that populates a gridview using sqldatasource.
I want to be able to click on the select hyperlink on a row and use that event to populate ANOTHER gridview based on the ID of the product category that is clicked. E.g say the 'CDs' row is clicked, another gridview shows all the different CDs.
As a result, I need the select(sql) statement for the second table to be dynamic based on what the user clicks.
To be able to dynamically add a new datalist or a row to a gridview when placed in a foreach loop for example I have an SQL query that outputs the values for each time an ID number is in a list, but I need to a way to output them...
So could I create a new datalist or row for each one created?
I haven't had any luck finding the answer yet. My problem is that I want to be able to update the dataformatstring on a gridview column at runtime. For example, I switch from displaying # of units to cost of said units... and I want to change the format of the column to {0:c}. It seems like it should be a simple task.

I have a gridview and i'm associating the datasource for the grid view dynamically at runtime
I mean
gridView2.DataSource = titlesArrayList;
gridView2.DataBind();
And i want the data in cells of this grid view to be centered, right now they are left-justified
If i was associating data through
<asp:BoundField />
I have this property
ItemStyle-HorizontalAlign="Center"
But how can i access this property if the gridview is associated dynamically
how to add the footer row dynamically in gridview. with textboxes..
View 3 RepliesI'm working on an ASP.Net page containing a GridView, which is populated with customer orders returned by a stored procedure. What I'd like to do is dynamically change the backcolor of the GridView rows to indicate priority.
The stored procedure returns an integer indicating the records priority, I think I just need to translate the integer to a color, then make the GridView row display it.
The "making the GridView row display it" part is the one that's giving me a hard time.
What's the best way to do this?
I've created a gridview dynamically, now i want to fire an event when the selectedindex has changed.
GridView NewDg = new GridView();
NewDg.ID = "SubGridView" + e.Row.RowIndex.ToString();
NewDg.DataKeyNames = new string[]{"logentry_id"};
NewDg.SelectedIndexChanged += new EventHandler(NewDg_SelectedIndexChanged);
NewDg.RowDataBound += new GridViewRowEventHandler(NewDg_RowDataBound);
The RowDataBound works but it doesn't produce the right postback URL i guess.
In the RowDataBound i have the following code:
GridView sendingGridView = (GridView)sender;
e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(sendingGridView, "Select$" + e.Row.RowIndex);
this produces the following code:
javascript:__doPostBack('SubGridView4','Select$0')
Only this doesn't lead to the postback to this function:
void NewDg_SelectedIndexChanged(object sender, EventArgs e)
{
GridView sendingGridView = (GridView)sender;
ViewDetails(Convert.ToInt32(sendingGridView.SelectedDataKey["logentry_id"].ToString()));
}

View 2 RepliesI have a gridview and i need to add chekbox dynamically for each data set to select a particular row or dataset.
View 1 RepliesI have seen code for adding columns at runtime but here is another scenario for you. I am using a SQLDatasource control for my gridview. And the data returned can have different columns based on the filter meaning one time I may have a column A1, A2, A3 and another time I may have A2, A3, A4. Is there any way I can look at the columns when it is binded at the beginning and add the columns first?
I really need to use the SQLDatasource though because I am connecting to an AS400 and it is using a connection already made in the webconfig and do not know any other way. I do if it was MSSQL server but not this.

View 1 RepliesI'm having an issue with trying to add a button to my grid. My GridView is first loaded with data in the PageLoad event.
I'm then taking the data in the first cell of each row, and creating a button that will link to a URL. To get the URL, I have to run a query with the data in the first cell as a parameter. I was doing this in the RowDataBound event at first, but hitting that query for every row was making it really slow.
So I decided to add a button that would retrieve the URL only when you clicked the button.
Here's my GridView:
[Code]....
The grid generates fine, the button gets added to the grid for each row. But when I click on it, the RowCommand event doesn't fire, and the page just refreshes.
i have a gridview with 5 columns and last column is a button column.....
now by clicking on dat button i need to add a new empty row with last column as btncolumn like prevs row
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
[Code]....
the row used to get in edit mode only if i edit the next row means first row never get in edited mode.
I have a situation where I needed to add a row to my gridview. So say I have rows 3, 4 and 5.
My Datakeys are defined as "ID, CostingID". I did that so I can reference the two ID values I need when saving records.
here is the code in my RowDataBound event.
Basically if it is a datarow, I'm adding the value dataitems so I can get a sub total in the footer row.
Then, I have a boolean field called isDisbursement. So I sort my data by that field. So all records with the disbursement flag as true will display first.
Then as soon as the disbursement flag hits false I add a row to display the Total of the disbursement records value field.
All this works. My problem is, because I added a row at index 4 it inherits the datakey of the row that was at index 4 before. So when I'm looping through the grid rows to save the values I'm having a problem. I've attached an image so you will understand better what I'm trying to achieve. The "Total Disbursements" is the row I added. But it gets the following rows datakey because it is now at index 4.
when I do this, as soon as I reach row 4, although it doesn't have a CostingID it gets the CostingID of row 5 that used to be row 4:
Code:
Dim CostingID As Long = Convert.ToInt64(Me.grvCostings.DataKeys(row.RowIndex).Values("CostingID").ToString)
Dim strValue As String = CType(row.FindControl("txtValue"), TextBox).Text
Code:
If e.Row.RowType = DataControlRowType.DataRow Then
If Not IsDBNull(DataBinder.Eval(e.Row.DataItem, "value")) Then
_SubTotal += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, _
"value"))
End If
[Code] ....
I'm adding a row to my gridview like this in the RowDataBound event
Code:
If (Not isDisbursementRowAdded) Then
Dim row As GridViewRow
Dim cell As TableCell
row = New GridViewRow(e.Row.RowIndex + 1, e.Row.RowIndex + 1, DataControlRowType.DataRow, DataControlRowState.Normal)
[code]...

View 1 RepliesI have created a gridview dynamically from scratch and added it to my aspx page. This works fine, but i have a button in the footer of on of the columns, which when clicked on makes the gridview disappear and doesn't fire the onclick event that it should. This should obviously not be the case. My question is why does the event not fire and why does the gridview vanish? Bear in mind i have never created aa gridview in the code behind before, so excuse me if i am being dense

I coded in code behind to dynamically generate a gridview as the columns of the gridview changes based on user selection. In the gridview I have dynamically generated controls like textbox, dropdown list etc.I have a few filtering options about, for example: listbox which will postback on change and causes the gridview content to change as well.My problem is: since the controls are randomly generated and every postback will read dataset from database and reload, the naming of the controls are dynamically generated too.
