Hai I am using the following code to access columns in a row but always displays empty string when using Row.Cells[1].Text I am using this code in GridView Unload event handler.
Thanks inn advance.
foreach (GridViewRow row in grvSearchRingTone.Rows)
{
String coltext = row.Cells[1].Text;
}
I would suggest using the Gridview Databound event instead. Because the
Unload event occurs when the server control is unloaded from memory.
protected void GridView1_DataBound(object sender, EventArgs e)
{
foreach (GridViewRow row in grvSearchRingTone.Rows)
{
String coltext = row.Cells[1].Text;
}
}
Databound events occur after the server control binds to a data source.
To understand how gridview events work, look at MSDN
It could be done in Gridviews RowDataBound Event ie
protected void gvUsers_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
String coltext = e.Row.Cells[1].Text
}
else if(e.Row.RowType == DataControlRowType.DataRow)
{
String coltext = e.Row.Cells[1].Text
}
}
Hope this helps.

I have a datatable and it contains a website url and I am displaying entire data in gridview, I want to add hyperlink to all existing urls before binding to gridview.
I am getting data dynamically from database , So I use autogenenerate= true
is it possible ?
You can listen to the OnRowDataBound event and from there trying to infer which cells contain a URL and then, turn them into a link:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
foreach(TableCell cell in e.Row.Cells)
{
if (cell.Text.StartsWith("http"))
{
cell.Text = $"<a href='{cell.Text}'>{cell.Text}</a>";
}
}
}
}
i want to hide last 4 digits of mobile number in gridview and show last 4 digits as **** . im getting only header value not item template values. how to get mobile values/item values and edit it and assign to grid view?
protected void gvrequests_RowDataBound(object sender, GridViewRowEventArgs e)
{
string Mobile = e.Row.Cells[3].Text;
string securedPhone = Mobile .Remove(6);
string MobileSecured= securedPhone + "****";
e.Row.Cells[3].Text=MobileSecured
}
You need to check the row first that it is DataRow or not like this.
protected void gvrequests_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
// your logic will go here
}
}
protected void gvrequests_RowDataBound(object sender, GridViewRowEventArgs e)
{
foreach (TableCell tc in e.Row.Cells)
{
tc.Attributes["style"] = "border-color: #87CEFA";
}
if (e.Row.RowType == DataControlRowType.DataRow)
{
string Mobile = e.Row.Cells[3].Text;
string securedPhone = Mobile .Remove(6);
string MobileSecured= securedPhone + "****";
e.Row.Cells[3].Text = MobileSecured;
}
}
RowDatabBound even fired on each row means for header row , data row (alternate row too) and footer row.
So, when you want to manipulate the data, as #Sain suggest, you check that it is datarow then our logic implement.
The same logic is also apply for header and footer, but ideally we should use for the data row only.
I am trying to get gvProducts row count.
I have tried the below code but it give insufficient result.
protected void gvProducts_RowCommand(object sender, GridViewCommandEventArgs e)
{
string commandName = e.CommandName.ToString().Trim();
GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
if (row.Controls.Count == 1)
{
//my code
}
}
You want total rows in Gridview? Use Count property:
gvProducts.Rows.Count
Update:
To find the rows count of nested gridview, you can use the RowDataBound event of parent gridview:-
protected void gvProductsParent_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
GridView gvProducts = (GridView)e.Row.FindControl("gvProducts ");
int count = gvProducts.Rows.Count;
}
}
Please note this event will fire for each row present in your parent gridview this the count will change according to each row.
I have GridView with 2 columns.
The first column is: test-label (TemplateField)
The second: checkbox (asp:CheckBoxField) that connect to sql table with bit column (done).
I want that on page load - the page will check every row, where the checkbox = true, the test-label.visble will be false.
I know how to write code with SELECT statement to check the value from the SQL table, but don't know how to check every row on the gridview on the page-load.
how can I do that?
(i can't use findcontroll for the checkbox because it's checkboxfield and not just "checkbox".
<asp:CheckBoxField DataField="done" SortExpression="done" HeaderText="done?" />
so, what can I do here? maybe to replace that field with regular cb? (i don't know how to do there databind - on the regular cb).
you can use GridView.RowDataBound Event
so you can do something like
protected void GVRowDataBound(object sender, GridViewRowEventArgs e)
{
var check = (CheckBox) e.Row.FindControl("ID"); // ID is id of the checkbox
var lable = (Label) e.Row.FindControl("LableID");
if(check != null && lable != null)
{
if(check.Checked)
{
lable.Visible = false;
}
}
}
You can't do it in Page.Load because the GridView isn't databound yet.
Try handling GridView.RowDataBound.
Code:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox cb = (CheckBox)e.Row.FindControl("checkbox");
Label lbl = (Label)e.Row.FindControl("test-label");
lbl.Visible = !(cb.Checked);
}
}
The process I am doing is if lbl.Text is "Validated" then disable the checkbox accordingly in grid. The code works fine if paging is not there.
Now the problem is I am using paging and when I click to the next page of grid
the validated things appear with the checkbox enabled.
I checked through breakpoints. Its loading the previous gridpage values during page load event. And after pageloadevent its going design and loads the new values in grid.
//-------loading previous page values of grid here---------
protected void Page_Load(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView1.Rows)
{
Label lbl = (Label)row.FindControl("Labely8");
Label Label23 = (Label)row.FindControl("Label23");
CheckBox checkbox = (CheckBox)row.FindControl("chkRows");
if (lbl.Text == "Validated")
{
checkbox.Enabled = false;
}
else
{
checkbox.Enabled = true;
}
}
}
I think you need to do enable or disable each of the checkboxes individually in the GridView.RowDataBound event rather than all at once in the Page_Load event:
void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox checkbox = (CheckBox)e.Row.FindControl("chkRows");
checkbox.Enabled = e.Row.Cells["nameOfCellWithLabel"].Text == "Validated";
}
}
