I am using a linkbutton within a gridview control.I want to open the link into a new tab. Link button:
<asp:LinkButton ID="lbtnEditCompany" CssClass="ahrefSearch" Text="Select" runat="server" OnClick="lbtnEditCompany_Click" />
Source Code :
protected void lbtnEditCompany_Click(object sender, EventArgs e)
{
try
{
LinkButton button = (LinkButton)sender;
SiteID = button.CommandArgument;
DataSet set = DataAccess.GetAllCorporateSites(SearchbyAlphabet, SessionManager.SaleID, SearchbyAssociate);
string str = "";
for (int i = 0; (i < set.Tables[0].Rows.Count) && (str == ""); i++)
{
if (SiteID == set.Tables[0].Rows[i]["ID"].ToString())
{
str = set.Tables[0].Rows[i]["CompanyName"].ToString();
}
}
SessionManager.WidgetId = Convert.ToInt32(SiteID);
SessionManager.SalesPersonSiteName = str;
base.Response.Redirect("~/Corporate/WidgetDetails.aspx", false);
}
catch (Exception exception)
{
HandlePageError(exception);
}
}
Try below code
Response.Write(String.Format("window.open('{0}','_blank')", ResolveUrl("~/Corporate/WidgetDetails.aspx")));

ASP. net data grid show empty rows without text randomly. Though is shows empty rows, on double clicking on empty row, the data from the row gets populated correctly to another text box.
Below is the UI code.

<div class="grdCtl">

Also, this application is being used by many remote clients and it is hosted on IIS in a server.
Make sure the global variable mLocationData is not being altered elsewhere in the code. It seems that either this variable, or Session["DataRecords"] is being reset elsewhere.
If the page loads correctly the first time the page loads, and the records disappear on subsequent postbacks, that points to the datasource being altered.
How would I make this LinkButton in GridView non-clickable if it ends in a *.rpt filetype?
I'm not sure where and which conditions I should add.
Thanks in advance!

That is because its dynamically generated and it will lose its state after its rendered on your page.
To access the dropdown and its related events and properties, you will need to recreate it everytime your page is postback.
Hope its clear enough.
here i bind grid columns dynamically using code behind because my GetSocailAnalytics method return dynamic column according to parameter passed.after binding column of grid using data table my grd_OnRowCommand event not firing when i click on grid row. grid is successfully bind. can any one help me out this issue.here is my code...

The RowCommand event is raised when a button is clicked in the
GridView control.
it is not not firing when you click on grid row
solution is adding button (LinkButton) column to the gridview with CommandName ="Filter"
I am somewhat new to ASP.NET and I am confused by the syntax so I am a little lost. I am trying to hide/disable a button based on an if statement but I dont know how to disable or hide it. I have done C# before but this code looks unfamiliar to me.
Below is some of the code:
C# component:
protected override void Render(HtmlTextWriter writer)
{
string PostCtrl = Request.Params["__EVENTTARGET"];
if (PostCtrl == "AccColLocation_content$collisionLocation$EditColLocation")
{
valDropDownlist(((CustomControl.DropDownValidator)collisionLocation.FindControl("valLoc_municipality")), "CollisionLocation.municipality");
..............
}
}
HTML:
<ItemTemplate>
<asp:LinkButton ID="EditColLocation" runat="server" Text="Edit Collision Location" OnClick="CollisionLocation_Edit" />
</ItemTemplate>
valDropDownList Method:
protected void valDropDownlist(CustomControl.DropDownValidator valDropdown, string DataElement)
{
try
{
bool mvarRequired, srRequired;
DataTable dtDataElement = DBFunctions.DBFunctions.getDataElement(RepDateTime, DataElement);
string s = dtDataElement.Rows[0]["mvarRequired"].ToString();
mvarRequired = (dtDataElement.Rows[0]["mvarRequired"].ToString() == "True") ? true : false;
srRequired = (dtDataElement.Rows[0]["srRequired"].ToString() == "True") ? true : false;
valDropdown.HaveToSelect = (SelfReported) ? srRequired : mvarRequired;
}
catch (Exception err)
{
MessageBox("An error occurred while setting drop down validation rules. " + err.ToString());
}
}
All these buttons are in grid view.
I have something of this nature:
protected void deletedr(object sender, EventArgs e)
{
try
{
GridView gv = (GridView)FindControl("DriverInfo");
gv.DataSource = DBFunctions.DBFunctions.getInfo(ReportID.Value, "", 2); ;
gv.DataBind();
bool isSelectedLast = false;
DataTable dt = DBFunctions.DBFunctions.getInfo(ReportID.Value, "", 2);
if (dlDriverNo.SelectedValue == dt.Rows[dt.Rows.Count - 1]["DriverNo"].ToString())
{
isSelectedLast = true;
}
if (!(DBFunctions.DBFunctions.deleteDriver(ReportID.Value, dlDriverNo.SelectedValue, isSelectedLast)))
{
MessageBox(null);
}
else
{
dlDriverNo.Visible = false;
lblDelDriver.Visible = false;
delDriverconfim.Visible = false;
cancelDel.Visible = false;
dlDriverNo.Items.Clear();
gv.DataSource = DBFunctions.DBFunctions.getInfo(ReportID.Value, "", 2);
gv.DataBind();
}
}
catch (Exception err)
{
MessageBox("An error occurred while deleting the driver. " + err.ToString());
}
}
If your LinkButton is in a GridView, the most interesting problem is getting a handle on it. After you have a handle you can just set it to invisible or disabled:
linkButton.Visible = false;
or
linkButton.Enabled = false;
But to get a handle to the LinkButton control you will need to use .FindControl in a suitable event on the GridView control:
<asp:GridView ID="myGridView" runat="server" OnRowDataBound="myGridView_RowDataBound">
...
</aspGridView>
Then in the code behind you would have:
protected void myGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
var linkButton = (LinkButton)e.Row.FindControl("EditColLocation");
if (linkButton != null)
{
if (*your condition to check*)
linkButton.Visible = false;
}
}
Hope this will get you moving in the right direction.
you can try
valDropdown.Visible = false; //Mask the control
After the if condition write the below code.
Buttonname.visible=false;
