Add code to your BindGrid() method to re-bind datagridview to a new data.
Something like this:
// Set up the data source.
bindingSource.DataSource = GetData("Select * From Register");
GridView1.DataSource = bindingSource;
In your BindGrid data add following code
con.Open();
SqlCommand cmd = new SqlCommand("Select * from Register", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
con.Close();
if (ds.Tables[0].Rows.Count > 0)
{
Gridview1.DataSource = ds;
Gridview1.DataBind();
UpdatePanel1.Update();
}

hello all i am new to asp.net and i want to get values from grid view when i click on Edit or Delete or and i don't know how to do it i am sending data table to show table data and i don't want to use SQL Data Source from Visual tool box.
i have tried the following code but it gives error
protected void dgv1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Edit")
{
int rowindex = ((GridViewRow)((LinkButton)e.CommandSource).NamingContainer).RowIndex;
dgv1.EditIndex = rowindex;
dgv1.DataBind();
}
}
}
my view page code is as follows
<form id="form1" class="form-control form-group" runat="server">
<asp:Panel ID="pnlAddCustomers" runat="server" Height="376px">

and body pic is as follow
enter image description here
Try this:
LinkButton lnkBtn = (LinkButton)e.CommandSource; // the button
GridViewRow gvRow = (GridViewRow)lnkBtn.Parent.Parent; // the row
You may also get the data key index by adding DataKeyNames="MyTableKeyID" to the <asp:GridView /> tab, then
string selectedKeyIndex = this.GridView1.DataKeys[myRow.RowIndex]["MyTableKeyID"].ToString();
I am working on an etime application that has a drop-down list for paygroup and based on the pay group selected the employee drop down-list with in that paygroup is populated i then take the dates they have transactions for and do a min and max on those dates and fill the AvailableDateRange MIN-MAX. The question i have is i would like the calendar to only display the min and max date range for the from date and to date any thing greater than the max and anything less than the min should be greyed out.

I Tried This
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
if (e.Day.Date == DateTime.Parse(DropDownList3.Text))
{
e.Day.IsSelectable = true;
}
if (e.Day.Date < DateTime.Parse(DropDownList3.Text))
{
e.Day.IsSelectable = false;
}
}
You can do it by handling the DayRender event:
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
if (e.Day.Date > DateTime.Now) // use any selection criteria
{
// you can do all kinds of stuff here
e.Cell.Enabled = false;
e.Cell.ForeColor = Color.DarkGray;
}
}
This is what I have done for nested gridview :
The jQuery I have used to maintain this show hide is as:
<script type="text/javascript">
// Method for managing opening of gridview on + image and - image
$("[src*=plus]").live("click", function() {
$(this).closest("tr").after("<tr><td></td><td colspan = '999'>" + $(this).next().html() + "</td></tr>")
$(this).attr("src", "../Image/minus.gif");
});
$("[src*=minus]").live("click", function() {
$(this).attr("src", "../Image/plus.gif");
$(this).closest("tr").next().remove();
});
</script>

On server side this is what I am doing:

{
DataSet ds = new DataSet();
tBL objBL = new tBL();
GridViewRow editedRow = GridView1.Rows[e.NewEditIndex];
//now search row for your control...
GridView GridView3 = (GridView)editedRow.FindControl("GridView3");
GridView3.EditIndex = e.NewEditIndex;
objtxtToTableBL.ViewBL(dt);
GridView3.DataSource = dt;
GridView3.DataBind();
}
protected void GridView3_RowCancelling(object sender, GridViewCancelEditEventArgs e)
{
GridView1.EditIndex = -1;
}
protected void GridView3_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
}
I am binding the nested gridview on rowdatabound of GridView1 and that works fine.
The problem with all this is when I click on the edit button of innergridview(child) it get hide as the page postback .
What should I do so that when I click on its edit button the child gridview remains open and it gets hides only when I click on minus button. Please help it has already taken 3 days of mine.
I have a tabcontainer with two tabs:
The first tab contains a button.
The second tab contains a gridview that has three textboxes.
I would like to do the following: when one clicks on the button in tab1, the gridview in tab2 is populated with data in a prespecified csv file (note that the file has the same column names as the gridview).
This is what I have so far, but for some reason, the gridview doesn't get populated with the data in the csv.

Your code should not give any issues if you use :
fileContent.Length instead of fileContent.Count()
