I am doing a simple project on Visual Studio 2013 about a book library.
I have a database from which I will get the information for the GridView's.
The purpose of this page is to display the list of authors and their respective titles.
So, basically, I have a GridView which will display the author's names and IDs.
I added a column to the end and edited it as a template so I could include another GridView - this one will contain the book titles for the respective author in the first GridView.
The first GridView is connected to a first ObjectDataSource which will call a function GetData() (which will return the right table to be shown on the GridView).
The second GridView is connected to a second ObjectDataSource which will call a function GetTitlesByAuthor(). But, this function receives an argument: the au_id (author_ID).
My problem is: How can I pass the parameter au_id depending on the value of the au_id displayed on the first GridView rows?
EDIT: To be more clear:
I have a GridView with 3 columns (au_id, au_name, titles). I set the titles field to be a template so I could insert a gridview in the ItemTemplate section. That GridView will contain only a collumn with all the titles from a specific au_id (depending on the outter GridView row's au_id value). My problem is obtaining that value to send to the second ObjectDataSource containing a list of the titles.
So my final table would be something like:
au_id au_name titles
--------------------------
1 Gary A Book Title
Another Book I Wrote
2 Sarah Cooking book
Tech Book
... and so on ...
This is my current code:

ohh it's then nested gridview.I havent done work on objectdatasource but as I understand you have a main grid where you want to pass author id in child grid whuch shows books.
The way I would have done it..
protected void GVAuthor_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblauthid= (Label)e.Row.FindControl("lblCustomerID");//I dont know what is your grid source aspx so assuming it as label.
GridView GvBook = (GridView)e.Row.FindControl("GvBook");
bindChildGridview(Convert.ToInt32(lblauthid.Text), GvBook); //Bind the child gridview here ..
}
}
private void bindChildGridview(int authorId, GridView ChildGridview)
{
try
{
Get datasource based on authorId
ChildGridview.DataSource = <<Your Datasource>>; // Set DataSource Here
ChildGridview.DataBind();
}
catch (Exception) { }
}
The Select parameters for ObjectDataSources are stored in the InputParameters array. So, the value of the author id in the row needs to be added to this array.
Try this:
protected void GVAuthor_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
var authorId = e.Row.DataItem("au_id");
var ods = e.Row.FindControl("ObjectDataSource2") as ObjectDataSource;
ods.InputParamenters["author_ID"] = authorId;
}
}
You also may need to remove the DataSource attribute in GridView2 in the aspx page, set it dynamically in the rowDataBound event and then call DataBind as #coder001 does.
Here is nice approach described in msdn you can take a look objectdatasouce parameter.
I didn't want to change c# code.
So, to accomplish my goal I added an invisible Label next to the nested GridView, bound it to au_id and then configured the ObjectDataSource to get the parameter from the Label.
The resulting code is below:
<asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None" AutoGenerateColumns="False" DataKeyNames="au_id" DataSourceID="ObjectDataSource1" AllowPaging="True">

How to make any column hyperlinked (except first one) in dynamic gridview , where that hyperlink column is linked to another gridview.
This dynamic table shows two type of output as mentioned below:
View 1:
Start Bus_no Change_at Change_Bus_no Destination Means
Desu Office 715 Hanuman Mandir 781 Subroto Park DTC
Desu Office 715 Palam Airport 764 Subroto Park DTC
Desu Office 715 Palam Airport 781 Subroto Park DTC
View 2:
Start bus_no Destination Means
Subroto Park 764 Nehru Place Terminal DTC
In first view I want to make column 2nd (Bus_no) and 4th(Changed_Bus_no) and in second view I want to make column 2nd as hyperlink column which will be linked to another grid view table.

please help. Thanx in advance.
You can use Template Field for your requirement.
Try like this,
<asp:GridView ID="GridView1" runat="server" BackColor="White"

GridLines="Vertical" ForeColor="Black">

<SortedDescendingHeaderStyle BackColor="#575357" />
<Columns>
<asp:TemplateField HeaderText="First Column">

<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="#Gridview2"></asp:HyperLink>

You can do like this for all your columns.
I've got a GridView who's DataSource SELECTs based on the SelectedValue of another GridView.
On the GridView with the SelectedValue (DataKeyName), I need to execute the Select command when the grid loads, rather that using a "Select" button.
I've tried using the SelectedIndex attribute of the GridView but this wont do it for me.
I've also looked at various methods and events but I cant seem to find a good way of doing this.
In the code below, there is a ButtonField with a "Select" button but I would like the Select command to take place as or after the grid is populated.
Thanks in advance.

I am trying to have a gridview with dynamic data imported using a SqlDataSource , plus 2 TemplateFields containing 2 buttons as Accept and Decline.What I need to do is , update a specific column of the table where the records are coming from.(Change the value from Null to 1 or 0, in the column called "accepted")
Q.)I need a way to identify the row which the button will be clicked ?
(need to identify the value of access key for the particular row)

You are very close, just lack CommandArgument:
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="AcceptRequest" runat="server"
OnClick="AcceptRequest_Click" Text="Accept"
CommandName="AcceptRequestcmd"
CommandArgument="<%# Eval("request_no") %> />
</ItemTemplate>
</asp:TemplateField>
(assuming that request_no is the row identifier)
Then just
protected void GridView1_RowCommand(...)
{
switch ( e.CommandName )
{
case "AcceptRequestcmd" :
string rowid = e.CommandArgument;
}
}
I have this GridView that uses a custom data source:

How can I enable multiple select on it?
You can add CheckBox near evey row like code below and select multiple lines.
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox runat="server" ID="RowLevelCheckBox" />
</ItemTemplate>
</asp:TemplateField>

I am trying to update a gridview so that once a row has been deleted from it, it will then refresh and no longer show that row automatically. However this does not seem to be working.

<br />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="BookingsGridView" />
</Triggers>
</asp:UpdatePanel>
and then I am calling
UpdatePanel1.Update();
once the row is deleted sucessfully.
Why isn't this working?
If your have Read Method on Binding Data from database to your datagridview, just bind it again on your delete method.
something like this:
private void Read()
{
///binding stuff datagridview.datasource = datasource;
}
private void Delete()
{
//Your delete stuff
//call
Read(); // this will refresh your grid after deleting a record.
}
Best Regards
You need to bind the GridView once again after deleting the row. something like this.
public void GetData_BookingsGridView
{
.......//your code
BookingsGridView.DataSource=dt;
BookingsGridView.DataBind();
}
public void DeleteBookingGridView_Row()
{
//code for deleting gridview rows.
//now call GetData_BookingsGridView function to refresh GridView
GetData_BookingsGridView();
}
