asp.net C# passing value from gridview to texbox on button click

I have a simple gridview with button for each row, and I want to pass or display the value of user_full_name_ar in a label, I tried doing this using javascript function as shown below but it doesn't show the data it shows null,
gridview code:
<asp:Label ID="Label5" Text='transfer text here' runat ="server" />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="user_name" DataSourceID="SqlDataSource1" Height="100px" Width="383px">
<Columns>
<asp:BoundField DataField="user_name" HeaderText="user_name" ReadOnly="True" SortExpression="user_name" />
<asp:BoundField DataField="user_full_name_ar" HeaderText="user_full_name_ar" SortExpression="user_full_name_ar" />
<asp:TemplateField HeaderText="user_full_name_ar" SortExpression="user_full_name_ar">
<ItemTemplate>
<asp:Label ID="Label4" Text='<%# Session["lang"].ToString() == "en"? Eval("user_full_name_en") : Eval("user_full_name_ar") %>' runat ="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="ButtonSearch" runat="server" text="select" OnClientClick ="txt();" CommandArgument ='<%# Bind("user_name") %>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
javascript function to display value of label4 in gridview to label5 outside gridview :
<script type ="text/javascript" >
function txt() {
var t = document.getElementById("Label4");
document.getElementById("Label5") = t.value;
}
</script>

you can use a CommandField in gridview
<asp:Label ID="Label5" Text='transfer text here' runat ="server" />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="user_name" DataSourceID="SqlDataSource1" Height="100px" Width="383px">
<Columns>
<asp:CommandField HeaderText="select" SelectText="select " ShowSelectButton="True">
</asp:CommandField>
<asp:BoundField DataField="user_name" HeaderText="user_name" ReadOnly="True" SortExpression="user_name" />
<asp:BoundField DataField="user_full_name_ar" HeaderText="user_full_name_ar" SortExpression="user_full_name_ar" />
<asp:TemplateField HeaderText="user_full_name_ar" SortExpression="user_full_name_ar">
<ItemTemplate>
<asp:Label ID="Label4" Text='<%# Session["lang"].ToString() == "en"? Eval("user_full_name_en") : Eval("user_full_name_ar") %>' runat ="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>

Grid hat 3 ImageButtons for detail view, editing and deleting per row. DetaliView Button adds additional Table with data to the Page. Editing makes this Table editable. If the grid is sorted and any of those buttons is beeing clicked, Page loads and any sorting is lost.
How can I maintain the sort setting in PostBack after clicking any of those buttons?

How to disable LinkButton within GridViewclick from Client Side using JavaScript?

I have a GridView, In one column I have LinkButton control. I want to disable click from client side for certain condition on this column. Means for some rows it will not be possible for User to call onclick event and for some rows it is possible.
I want to achieve this from client side using javascript.
Or When User clicks on link, It will notify the User that this action can't be completed for this row.

In GridViewMultiplePOSAssociationId there is one column "Status" which has label LabelStatusPendingPOSId, LabelStatusPendingPOSId text is set Applied, Not Applied at the time of Binding. For Rows which has Status Applied, User should not be able to click on LinkButton Associate/Replace else He is allowed to click.

use this code OnRowDataBound for Your Grid
protected void grdViewCustomers_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType==DataControlRowType.DataRow)
{
LinkButton LinkbtnPOSId=(LinkButton)e.Row.FindControl("LinkbtnPOSId");
Label LabelStatusPendingPOSId = (Label)e.Row.FindControl("LabelStatusPendingPOSId");
Boolean boolStatus = LabelStatusPendingPOSId.Text == "Applied" ? true : false;
//LinkbtnPOSId.Attributes.Add("onclick", "function CheckStatus('" + boolStatus.ToString() + "')");
LinkbtnPOSId.Enabled = boolStatus;
}
}

Try this..
You can loop through the Gridview and make the particular control disable...
I am writing the code in javascript pageload function...
function PageLoad(sender, args)
{
for (var i = 0; i <= RowCount; i++)
{
document.getElementById('Gridview1_HyperLinkAssociate_' + i.toString() + '').disabled = true;
}
}
Set RowCount as the number of rows of the Gridview...

now in the link button i want to click it and retrieve that row's data in the same page and show it...
i am using

{
string rowID = (string)this.wbsdataGV1.SelectedDataKey.Value;
con.Open();
SqlCommand cmd = new SqlCommand(" select WBSCode,Description,TerritoryCode,AmountReleased from WBS where WBSCode='"+rowID+"'");
cmd.Connection = con;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
if (dt.Rows.Count > 0)
{
wbssearchdata1.DataSource = dt;
wbssearchdata1.DataBind();
}
con.Close();
}
this code but its not firing on the click .. so how can i solve this.. any help?

From your code I couldn't see anywhere you specified the button that fires the SelectedIndexChanged event. You'll need to do these
<asp:GridView OnSelectedIndexChanged="wbsdataGV1_SelectionChanged"
AutoGenerateSelectButton="true" />
Or
<asp:GridView OnSelectedIndexChanged="wbsdataGV1_SelectionChanged">
<Columns>
<asp:CommandField ShowSelectButton="true" />
</Columns>
</asp:GridView>
Or
<asp:GridView OnSelectedIndexChanged="wbsdataGV1_SelectionChanged">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton runat="server" ID="Selecting" CommandName="Select" Text="Select Row"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

{
TextBox txtRegion1 = (TextBox)ResultGridView.FooterRow.FindControl("txtRegion1");
TextBox txtNatureOFWork1 = (TextBox)ResultGridView.FooterRow.FindControl("txtNatureOFWork1");
if (txtRegion1.Text != "")
{
cmd.Connection = conn;
cmd.CommandText = "INSERT INTO RegionAndProjectInfo(RegionProjectName, NatureOFWorkID ) Values('" + txtRegion1.Text + "', '" + ddlnatureOfWork.SelectedValue.ToString() + "')";
conn.Open();
cmd.ExecuteNonQuery();
}
FillVendorGrid();
conn.Close();
}
}

You must use
Response.Redirect("Default3.aspx?ID=" + e.CommandArgument.ToString());
instead of Server Transfer, cause Server Transfer does a different thing compared to Response.Redirect.
The Server.Transfer method also has a second parameter—"preserveForm". If you set this to True, using a statement such as
`Server.Transfer("Default3.aspx?ID=" + e.CommandArgument.ToString()`, True);
, the existing query string and any form variables will still be available to the page you are transferring to.
its more of a file transfer, instead of a redirect
http://msdn.microsoft.com/en-us/library/ms525800%28v=vs.90%29.aspx

<ItemTemplate>
<asp:hyperlink id="LinkButton3" navigateurl='<%# "Default3.aspx?ID=" + Eval("RegionProjectID")%>' text='<%# Bind("RegionProjectName")%>' runat="server" />
</ItemTemplate>
I had updated the itemtemplate of Regionprojectname as above and now getting query string .
