Edit on child gridview collapse the expansion

Edit on child gridview collapse the expansion - c#

I have a parent grid GVInvoiceDet. CRUD operation on this grid is working fine. In each row of the parent, I have child grid GVTaxDetails which opens on click of image ie expand/collapse feature.
I am looking for CRUD within child grid also. But when I click on edit within child, the texbox for editing doesn't appear and the parent grid collapses.
Here is child grid rowediting code
protected void GVTaxDetails_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView gvTemp = (GridView)sender;
gvUniqueID = gvTemp.UniqueID;
//gvEditIndex = e.NewEditIndex;
gvTemp.EditIndex = e.NewEditIndex;
GVInvoiceDet.DataBind();
}
Parent row editing code
protected void GVInvoiceDet_RowEditing(object sender, GridViewEditEventArgs e)
{
GVInvoiceDet.EditIndex = e.NewEditIndex;
GVInvoiceDet.DataBind();
BindItemGrid();
}
ASPX file :

I got the work done... Posting the code for others if come across similar situation.
In parent rowdatabound have added code to keep the div open and update the editIndex.
protected void GVInvoiceDet_RowDataBound(object sender, GridViewRowEventArgs e) {
GridViewRow row = e.Row;
if(row.RowType == DataControlRowType.Header)
{
return;
}
else if (row.RowType == DataControlRowType.DataRow )
{
//Find Child GridView control
GridView gvTax = new GridView();
gvTax = (GridView)row.FindControl("GVTaxDetails");
if (gvTax.UniqueID == gvUniqueID)
{
gvTax.EditIndex = gvEditIndex;
//Expand the Child grid
ClientScript.RegisterStartupScript(GetType(), "Expand", "<SCRIPT LANGUAGE='javascript'>expandcollapse('div" + ((DataRowView)e.Row.DataItem)["itemcd"].ToString() + "','one');</script>");
}
}
}
expandcollapse is function on aspx side:
function expandcollapse(obj, row) {
var div = document.getElementById(obj);
var img = document.getElementById('img' + obj);
if (div.style.display == "none") {
div.style.display = "block";
if (row == 'alt') {
img.src = "Images/minus.png";
}
else {
img.src = "Images/minus.png";
}
img.alt = "Close View Taxes";
}
else {
div.style.display = "none";
if (row == 'alt') {
img.src = "Images/plus.png";
}
else {
img.src = "Images/plus.png";
}
img.alt = "Expand View Taxes";
}
}

This is the code to export:
public void ExportDataToExcel(object sender, EventArgs e)
{
GridView1.AllowPaging = false;
GridView1.AllowSorting = false;
GridView1.AutoGenerateEditButton = false;
GridView1.AutoGenerateDeleteButton = false;
Response.ClearContent(); //Clear any content
Response.AppendHeader("content-disposition","attachment; filename=Usuarios.xls"); //Export as XLS (Excel)
Response.ContentType = "application/excel";
StringWriter stringWriter = new StringWriter();
HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter); //Saves all the content including rows.
GridView1.RenderControl(htmlTextWriter);
Response.Write(stringWriter.ToString()); //Gridview data is going to be converted for a xls file
Response.End();
}
This is what I get:
Like I said on the title, I want to hide TextBox and buttons while exporting to excel in order to only see the data. Those controls are inside EditItemTemplate tags. On the aspx website the GridView show data from SQL server database, what I want to do is to export it as a table.

Unable to get gridview footer values in RowCommand

I'm creating a page to enter employee's leave details in a dynamic gridview. Entry of data will be done by the from the footer of the gridview. When I try to get the values from the footer, all the text values as well as other values are coming as null or "".
Here is the code of RowCommand:
protected void gvEmployeeDetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("ADD"))
{
TextBox txtAddEmpID = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddEmpID");
RadioButtonList rblFooter = (RadioButtonList)gvEmployeeDetails.FooterRow.FindControl("rblFooter");
TextBox txtAddDoj = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddDoj");
TextBox txtAddLeaves = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddLeaves");
TextBox txtAddDesignation = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddDesignation");
conn.Open();
string cmdstr = "insert into tblLeaves(EmpId,IsActive,DOJ,Leaves,Designation) values(#EmpId,#IsActive,#DOJ,#Leaves,#Designation)";
SqlCommand cmd = new SqlCommand(cmdstr, conn);
cmd.Parameters.AddWithValue("#EmpId", txtAddEmpID.Text);
cmd.Parameters.AddWithValue("#IsActive", rblFooter.SelectedValue);
cmd.Parameters.AddWithValue("#DOJ", txtAddDoj.Text);
cmd.Parameters.AddWithValue("#Leaves", txtAddLeaves.Text);
cmd.Parameters.AddWithValue("#Designation", txtAddDesignation.Text);
cmd.ExecuteNonQuery();
conn.Close();
BindData();
}
}

Please correct me where I'm going wrong.

You are not using sender in your find control code line. Try to replace below line.
TextBox txtAddEmpID = (TextBox)gvEmployeeDetails.FooterRow.FindControl("txtAddEmpID");
this.
protected void gridview_RowCommand(object sender, System.Web.UI.WebControls.GridViewCommandEventArgs e)
{
if (e.CommandName == "Add") {
TextBox txtAddEmpID = (TextBox)((GridView)sender).FooterRow.FindControl("txtAddEmpID");
}
}

While Updating the Rows in grid , I am getting the below error message.

Guide me how to fix this error. Thanks in advance.

You need to add an update method to your gridview. Look at this tutorial: Gridview ObjectdataSource

I can not find the controls of lblCategoryName and ddlBlogCategoty the Edit button click in Gridview

How can I find the controls lblCategoryName and ddlBlogCategory?
Here is my code:

{
Label lblAccount = (Label)e.Row.FindControl("lblCategoryName");
string s = lblAccount.Text;
DropDownList ddlBlogCategory = (DropDownList)e.Row.FindControl("ddlBlogCategoty");
DAO.DAO dao_category = new DAO.DAO();
DataTable dt_blog_cat = dao_category.SelectCategory();
if (ddlBlogCategory != null)
{
// ddlBlogCategory.Items.Clear();
ddlBlogCategory.DataSource = dao_category.SelectCategory();
ddlBlogCategory.DataTextField = "CategoryName";
ddlBlogCategory.DataValueField = "BlogCategoryID";
ddlBlogCategory.DataBind();
}
}
