How to make column Editable in Gridview

Please send the full code with HTML. 

Hi RajKiran

  I have attached image . Textbox should appear on right side of Gridvew SessionDate column. It is creating another column

Thanks

In order to make the "SessionDate" column editable, you can use a TemplateField instead of a BoundField. Here's an example of how you can modify the code to achieve this:

protected void grdPlanning_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    DataTable dt = sQLUtility.GeBookPlanningRecommendation(HRpl, BookCollection, StudentCollection).Tables[0];
    GridViewRow row = grdPlanning.Rows[e.RowIndex];
    TextBox txtSessionDate = (TextBox)row.FindControl("txtSessionDate");
    dt.Rows[row.DataItemIndex]["SessionDate"] = txtSessionDate.Text;
    sQLUtility.UpdateBookPlanningRecommendation(dt);
    grdPlanning.EditIndex = -1;
    BindGrid();
}

Hi Rajkiran

  I have dynamic columns . These 2 columns i have added after the Dynamic columns. Code shared above. I have autogenerate columns = true

I want SessionDate to be editable only.

Thanks

SQLUtility sQLUtility = new SQLUtility();
DataTable dt = sQLUtility.GeBookPlanningRecommendation(HRpl, BookCollection, StudentCollection).Tables[0];
if (dt != null)
{
    grdPlanning.DataSource = dt;
    grdPlanning.DataBind();
}

asp.net

Is it windows or asp.net ?

Hi RajKiran

  It is giving error - The type or namespace name GridViewColumn could not be found

GridViewColumn sessionDateColumn = grdPlanning.Columns["SessionDate"];

Thanks

To make the "SessionDate" column editable in all rows of a GridView, you can set the `ReadOnly` property of the corresponding column in the `GridView.Columns` collection to `false`. Here's an example:

```
// Bind the DataTable to the GridView
grdPlanning.DataSource = dt;
grdPlanning.DataBind();

// Make the "SessionDate" column editable
GridViewColumn sessionDateColumn = grdPlanning.Columns["SessionDate"];
sessionDateColumn.ReadOnly = false;
```

In the above code, we first bind the DataTable `dt` to the GridView `grdPlanning`. Then, we get the `GridViewColumn` corresponding to the "SessionDate" column and set its `ReadOnly` property to `false`, which makes the column editable in all rows of the GridView.

GridViewColumn sessionDateColumn = grdPlanning.Columns["SessionDate"];

// Create a DataTable with the required columns
DataTable dt = new DataTable();
dt.Columns.Add("SessionDate", typeof(DateTime));
dt.Columns.Add("Remarks", typeof(string));

// Populate the DataTable with data
dt.Rows.Add(DateTime.Today.AddDays(1), "Row 1 Remarks");
dt.Rows.Add(DateTime.Today.AddDays(2), "Row 2 Remarks");
dt.Rows.Add(DateTime.Today.AddDays(3), "Row 3 Remarks");

// Bind the DataTable to the GridView
grdPlanning.DataSource = dt;

// Make the "SessionDate" column editable
GridViewColumn sessionDateColumn = grdPlanning.Columns["SessionDate"];
sessionDateColumn.ReadOnly = false;

// Bind the GridView
grdPlanning.DataBind();
