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">
<asp:Label ID="lblAddCustomers" runat="server" Text="Add Customers"></asp:Label>
<br runat="server"/>
<asp:Label ID="labelAddName" Text="Customer Name" runat="server"></asp:Label>
<asp:TextBox ID="txtboxcustomername" runat="server" Height="16px"></asp:TextBox>
<asp:Label ID="Label1" runat="server" Text=" Customer City "></asp:Label>
<asp:TextBox ID="txtboxcity" runat="server"></asp:TextBox>
<asp:Label ID="Label2" runat="server" Text=" Customer Telephone "></asp:Label>
<asp:TextBox ID="txtboxtelephone" runat="server"></asp:TextBox>
<br />
<asp:Button ID="Button1" runat="server" Text="Add Customers" Height="57px" Width="208px" OnClick="Button1_Click" />

</asp:GridView>
</asp:Panel>
</form>
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();

Data Successfully updated in table,after the insert gridview is not listing the latest record,if i refresh the page again the data will shown.please help ...........
protected void Btnsubmit_Click(object sender, EventArgs e)
{OleDbConnection conn = new OleDbConnection(); conn.ConnectionString =ConfigurationManager.ConnectionStrings["conn"].ToString();conn.Open();
string query = "insert into Register
(Code,Author,AER,PublishDate) values('" + txtcode.Text + "','" +

OleDbCommand cmd = new OleDbCommand(query, conn);
cmd.ExecuteNonQuery();
conn.Close();
BindGrid();
Clear();
}
protected void BindGrid()
{
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();
}
I have a GridView control, and inside of this control I have defined a link button using GridView.ItemTemplate.
I am using this to open a new window on click. When I click on the link button, however, the page refreshes before opening the new window.
How can I stop the page from refreshing after the link button is clicked?

LinkButton lnk = e.Row.FindControl("ppp") as LinkButton;

}
I would not use a LinkButton, but a straight html link.
<ContentTemplate>
<a href="#" ID='<%#Eval("product code")%>' onclick="doSomething();">
<%#Eval("productcode")%>
</a>
</ContentTemplate>
And then you can define some javascript in the page.
function doSomething(ProductCode) {
// enter the code here to open the window
}
Also, I would stay away from using UpdatePanel, but that's just my preference.
I have a grid view within a grid view. When I click on edit of parent grid view the child grid view displays a checkbox. When I click on next page button of child grid view the controls that were made visible become invisible again. This is not the behaviour I require. I would like the controls that are made visible by clicking edit to remain visible through paging of the child grid view while parent grid view is in edit mode.

For anyone who wants to know, I disabled paging of the child grid when edit button is clicked so all check boxes show on all rows of child grid now.
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:
protected void GridView3_RowEditing(object sender, GridViewEditEventArgs e)
{
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()
