A part of this should be done at RowDataBound also.
Here is some sample code
private static DataSet ds;
private const string query = "select * from tblcountrynames";
protected void grdViewCInfo_RowEditing(object sender, GridViewEditEventArgs e)
{
grdViewCInfo.EditIndex = e.NewEditIndex;
//guessing that this is your databind event
dbLoad();
}
protected void grdViewCInfo_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowState == DataControlRowState.Edit)
{
//your ddl
DropDownList ddl = (DropDownList)e.Row.FindControl("ddlCountry");
PopulateCountries(ddl, query);
//grdViewCInfo.Rows[e.NewEditIndex].Cells[4].Controls.Add(ddl);
}
}
private void PopulateCountries(DropDownList ddl, string query)
{
if(ds!= null && ds.Tables[0].Rows.Count >0)
MySqlConnection objMycon1 = new MySqlConnection(strProvider);
//commenting open; as adapter doesn't need connection to be open
//objMycon1.Open();
MySqlCommand cmd1 = new MySqlCommand(query, objMycon1);
MySqlDataAdapter da = new MySqlDataAdapter(cmd1);
ds = new DataSet();
da.Fill(ds);
objMycon1.Close();
objMycon1.Dispose();//comment if objMycon1 is not IDisposible
}
if (ds.Tables[0].Rows.Count > 0)
{
ddl.DataSource = ds;
ddl.DataTextField = "Name";
ddl.DataValueField = "ID";
ddl.DataBind();
}
}
This is how it should be done.
Hope this helps.
What does (DropDownList)grdViewCInfo.Rows[e.NewEditIndex].Cells[4].FindControl("ddlCountry"); return , is ddl set?
I reckon not. Perhaps there is no "ddlCountry" control in that cell.
Its a curious coincidence that the line,
//grdViewCInfo.Rows[e.NewEditIndex].Cells[4].Controls.Add(ddl);
is commented out below.
Do you have a drop down list in your EditItemTemplate?
Edit: I don't think you are actually in edit mode in the RowEditing event. If you move your code down to the RowCommand,
Then check for the Edit command. Wrap your code in something like,
if(e.CommandName == "Edit")
{
// do your edit here.
}
Though keep your grdViewCInfo.EditIndex = e.NewEditIndex; line, as you need that there.

I have a grid view control in my page that indexes all the Lecture Contents. I have added a Text Box control and a Link Button. But for the Lectures that have no Content yet, the Grid View does not appear.
Have tried many references, as a result the footer has appeared but I am not able to insert data using the Controls in the footer.
My main objective is to make the Controls behave same in both scenarios.
Here is the Grid View Code.
`<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" EmptyDataText="No Contents found for this lecture." ShowFooter="true" HeaderStyle-Wrap="false" Width="70%" CssClass="Grid" AlternatingRowStyle-CssClass="alt" PagerStyle-CssClass="pgr" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">

and the code behind functions for grid view.
`protected void Page_Load(object sender, EventArgs e){
if (Session["fac_username"] != null)
{
String username = Convert.ToString(Session["fac_username"]);
if (!IsPostBack)
{
BindGridViewData();
}
}

}

int lecID = Convert.ToInt32(Session["lecID"]);

GridView1.DataBind();} protected void GridView1_SelectedIndexChanged(object sender, EventArgs e){
}

int lecID = Convert.ToInt32(Session["lecID"]);
con.Open();
SqlCommand command = new SqlCommand("insert into uni_lect_content(lecc_id, lecc_contents) values(#lecc_id, #lecc_contents)", con);
command.Parameters.AddWithValue("#lecc_id", lecID);
command.Parameters.AddWithValue("#lecc_contents", ((TextBox)GridView1.FooterRow.FindControl("txtcontent")).Text);
command.ExecuteNonQuery();
con.Close();
lblmsg.Text = "New Course Successfully Created..!";}`
DataAccessLayer class's getAllConents() method is here.
`public class AllContents
{
public long lecc_id { get; set; }
public string lecc_contents { get; set; }
}
public class DataAccessLayer
{

using (SqlConnection con = new SqlConnection(cs))

con.Open();

obj.lecc_id = Convert.ToInt32(rdr["lecc_id"]);
obj.lecc_contents = rdr["lecc_contents"].ToString();
listAll.Add(obj);
}
}
return listAll;
}`
Help me out of this situation.
Thanks in advance.

please let me know where im goin wrong. im unable to get the perfect solution for this from past 1 week... its getting headache thing ..
getting error "input string is not in correct format" at commented line of reports.cs file
You're querying the database with Session["TaskId"] and you're showing task id on UI from query string. Are you sure that both are same?
I think you might want to use taks id from query string rather than session.
objc.TaskID = Convert.ToInt32(Request.QueryString["TaskID"]);
Update -
Filter the table based on your query string
rep.Tables[0].Select(string.Format("TaskID={0}", Request.QueryString["TaskID"]));

now in the link button i want to click it and retrieve that row's data in the same page and show it...
i am using
protected void wbsdataGV1_SelectionChanged(object sender, EventArgs e)
{
string rowID = (string)this.wbsdataGV1.SelectedDataKey.Value;
con.Open();
SqlCommand cmd = new SqlCommand(" select WBSCode,Description,TerritoryCode,AmountReleased from WBS where WBSCode='"+rowID+"'");
cmd.Connection = con;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
if (dt.Rows.Count > 0)
{
wbssearchdata1.DataSource = dt;
wbssearchdata1.DataBind();
}
con.Close();
}
this code but its not firing on the click .. so how can i solve this.. any help?
From your code I couldn't see anywhere you specified the button that fires the SelectedIndexChanged event. You'll need to do these
<asp:GridView OnSelectedIndexChanged="wbsdataGV1_SelectionChanged"
AutoGenerateSelectButton="true" />
Or
<asp:GridView OnSelectedIndexChanged="wbsdataGV1_SelectionChanged">
<Columns>
<asp:CommandField ShowSelectButton="true" />
</Columns>
</asp:GridView>
Or
<asp:GridView OnSelectedIndexChanged="wbsdataGV1_SelectionChanged">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton runat="server" ID="Selecting" CommandName="Select" Text="Select Row"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

Try this:
<asp:LinkButton ID="lnkeinfo" runat="server" CausesValidation="false" CommandName="Info"
CommandArgument='<%# Bind("Loan_ID") %>'>Information</asp:LinkButton>
Why don't you use a RESTful architecture to not save those parameters in Session and make pages kind'ev tightly coupled? Just create links named Info in your Grid instead of buttons (which post back data) with those parameters appended to the end of them as querystring. This is nicer approach and the result is the same.

Hi All,
In above written code only EDIT event is being fired & that is only once after that UPDATE,CANCEL no event is being fired. What am i doing wrong?All I want to do is change the GridRow Color on the basis of the value entered in QTY field.
I figured out the problem. The event was not firing because of the same IDs that i had given to the Label in each row. Hope this helpful to someone.
Not sure about your use of IsPostBackEventControlRegistered - I havent seen it used before but it seems that probably you are wiping out your update event by DataBind() every time in Page_Load().
Page_Load is fired every time the page loads which is then changing what the page is doing by resetting the grid.
Try wrapping the control in:
if(!IsPostBack)
{
// bind
}
so that it only does this on the first page load.
