[Solved] Need to get the values from the Text box's dynamically created in RadGrid

[Anto (DLL Version : 2008.3.1314.35)]

Hi All,

Have a RadGrid in aspx page. Have dynamically created GridTemplateColumn with Textboxes inside.

Works fine. I am able to enter values in the Textbox.

Here is the aspx coding.

<telerik:RadGrid ID="RadGridText" runat="server" Skin="Vista" AutoGenerateColumns="false"
                    OnItemDataBound="RadGridText_ItemDataBound" OnNeedDataSource="RadGridText_NeedDataSource"
                    OnPreRender="RadGridText_PreRender" Height="250px" Width="1000px">
                    <MasterTableView HeaderStyle-CssClass="disable-highlight" Width="98%" HeaderStyle-HorizontalAlign="Center"
                        HeaderStyle-Wrap="true">
                        <Columns>

                        </Columns>
                    </MasterTableView>
                    <ClientSettings Scrolling-AllowScroll="true" Resizing-AllowColumnResize="true" Scrolling-SaveScrollPosition="true"
                        Scrolling-FrozenColumnsCount="2" Scrolling-UseStaticHeaders="true">
                        <Selecting AllowRowSelect="true" />
                        <Scrolling AllowScroll="true" UseStaticHeaders="true" />
                    </ClientSettings>
                </telerik:RadGrid>

Here is the .cs coding

public void LoadGridText()

            dt1 = GetData();
            dtnewd = dt1.Tables[0].Clone();

            {
                boolValue = new TextBox();
                boolValue.ID = colname;
                boolValue.Width = 50;
                container.Controls.Add(boolValue);

                TextBox cBox = (TextBox)sender;
                GridDataItem container = (GridDataItem)cBox.NamingContainer;
            }

        }

I Need to get the entered values in the Textboxes. Need it as a DataTable when a button is clicked.

protected void btnCalc_Click(object sender, EventArgs e)
       {
           DataTable Dt = new DataTable();

           //Need to get the values in the Grid in this DataTable Dt.


       }

Is there any option to get it.

Thank you.

Hi Anto,

Please try the following code snippet.

C#:

private class MyTemplate : ITemplate
    {
        protected TextBox textBox;
        private string colname;
        public MyTemplate(string cName)
        {
            colname = cName;
        }
        public void InstantiateIn(System.Web.UI.Control container)
        {
            textBox = new TextBox();
            textBox.ID = "TextBox1";
            container.Controls.Add(textBox);
        }
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        DataTable sampleDataTable = new DataTable();
        sampleDataTable.Columns.Add("FirstColumn", typeof(string));
        DataRow sampleDataRow;
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            sampleDataRow = sampleDataTable.NewRow();
            TextBox txt = (TextBox)item.FindControl("TextBox1");
            string value = txt.Text;
            sampleDataRow["FirstColumn"] = value;
            sampleDataTable.Rows.Add(sampleDataRow);
        }
    }

Thanks,

Hi,

Displayed the Radgrid with Textboxes.            

Works fine. While entering the values. But not able to get the values from the Textboxes.

Added this code as Princy suggested. But error appeared "Object reference set to null"

Is there any option to get the values in a datatable.

Thanks

Hi Anto,

I'm not sure what your requirement is,but here "TextBox1" is the ID of the textbox control,which is a unique id.Usually we set unique names for different controls,else we may get an error.It is better to use different controls with unique names to identify them and make use of them better.
Please elaborate on your requirement,so that i may help.

Thanks,
Princy

Hi Anto,

Below is the full code snippet i tried.Please have a look at it.For the error ,please try setting EnableViewState="false".Let know if any concern.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server"  AutoGenerateColumns="false" AllowPaging="true" EnableViewState="false">
    <MasterTableView DataKeyNames="CustomerID">
    </MasterTableView>
</telerik:RadGrid>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

C#:

protected void Page_Init(object source, System.EventArgs e)
{
    DefineGridStructure();
}

private void DefineGridStructure()
{
    GridBoundColumn boundColumn = new GridBoundColumn();
    RadGrid1.MasterTableView.Columns.Add(boundColumn);
    boundColumn.DataField = "CustomerID";
    boundColumn.HeaderText = "CustomerID";

    string templateColumnName = "ContactName";
    GridTemplateColumn templateColumn = new GridTemplateColumn();
    templateColumn.ItemTemplate = new MyTemplate(templateColumnName);
    RadGrid1.MasterTableView.Columns.Add(templateColumn);
    templateColumn.HeaderText = templateColumnName;
}

private class MyTemplate : ITemplate
{
    protected TextBox textBox;
    private string colname;
    public MyTemplate(string cName)
    {
        colname = cName;

        textBox.ID = "TextBox1";
        container.Controls.Add(textBox);
    }

Hi Princy,

Have changed the function as

protected void btnCalc_Click(object sender, EventArgs e)
        {
 DataTable dt = new DataTable();
            int Textboxdynamicname = 1;
            int columncount = 0;
            //For Heading
            foreach (GridColumn column in RadGridText.MasterTableView.Columns)
            {
                if (!string.IsNullOrEmpty(column.UniqueName) && !string.IsNullOrEmpty(column.HeaderText))
                {
                    columncount++;
                    dt.Columns.Add(column.UniqueName, typeof(string));
                }
            }

            DataRow dr;
            foreach (GridDataItem item in RadGridText.MasterTableView.Items)
            {
                dr = dt.NewRow();

                for (int i = 0; i < columncount; i++)
                {
                    //For leaving First Two columns and Columns after 14
                    if (i < 2 || i > 14)
                    {
                        dr[i] = item[RadGridText.MasterTableView.Columns[i].UniqueName].Text;
                    }
                    else
                    {
                        //TextBox txt = (TextBox)item.FindControl("TextBox" + Textboxdynamicname);
                        TextBox txt = (TextBox)item[dt.Columns[i].ColumnName].FindControl("TextBox" + Textboxdynamicname);
                        string value = txt.Text;
                        dr[i] = value;
                        Textboxdynamicname++;
                    }
                }

                dt.Rows.Add(dr);
            }

        }

The values other than in Textbox comes. But if it is a Textbox errror appears.

Object reference not set to an instance of an object.

Line 1459:                        //TextBox txt = (TextBox)item.FindControl("TextBox" + Textboxdynamicname);
Line 1460:                        TextBox txt = (TextBox)item[dt.Columns[i].ColumnName].FindControl("TextBox" + Textboxdynamicname);
Line 1461:                        string value = txt.Text;
Line 1462:                        dr[i] = value;
Line 1463:                        Textboxdynamicname++;

Hi Anto,

Please try the below code snippet to access the textbox value.If any issue ,please let me know.

C#:

TextBox txt = (TextBox)item.FindControl(dt.Columns[i].ColumnName);
string value = txt.Text;

Thanks,
Princy

[Anto (DLL Version : 2008.3.1314.35)]

Princy,

Again got an error.

"Object reference not set to an instance of an object."

txt is always null. Think so the error is due to the Textbox is inside ItemTemplate.

Is there any other option to do this. 

Thank you.

-Anto

[Princy]

Hi Anto,

You are getting the “Object reference not set to an instance of an object” to the TextBox because the else block of the code is working for GridBoundCoumn as well. So before accessing the TextBox you can make sure that it is a GridTemplateColumn. Please try the following code and let me know if there is any issue.

C#:

DataRow dr;
foreach (GridDataItem item in RadGridText.MasterTableView.Items)
{
    dr = dt.NewRow();
    for (int i = 0; i < columncount; i++)
    {
        //For leaving First Two columns and Columns after 14
        if (i < 2 || i > 14)
        {
            dr[i] = item[RadGridText.MasterTableView.Columns[i].UniqueName].Text;
        }
        else
        {
            string columnType = RadGridText.MasterTableView.GetColumn(dt.Columns[i].ColumnName).ColumnType;
            if (columnType == "GridTemplateColumn")
            {
                TextBox txt = (TextBox)item.FindControl(dt.Columns[i].ColumnName);
                string value = txt.Text;
                dr[i] = value;
                Textboxdynamicname++;
            }
        }
    }
    dt.Rows.Add(dr);
}

Hope this helps.

Thanks,
Princy
