Hi Ramco, To create a reusable delete modal that can handle different tables (like Department and Banks) while being defined only once, you need a way to dynamically determine which table's record is being deleted. Here's how you can achieve that: 1. Create a Reusable User Control for the Modal 2. User Control Code-Behind: DeleteModal.ascx.cs using System; using System.Web.UI; namespace YourNamespace { public partial class DeleteModal : UserControl { public string DeleteMessage { get { return Label1.Text; } set { Label1.Text = value; } } public string TableName { get { return HiddenFieldTableName.Value; } set { HiddenFieldTableName.Value = value; } } public string RecordId { get { return HiddenFieldRecordId.Value; } set { HiddenFieldRecordId.Value = value; } } protected void lnkRecordDelete_Click(object sender, EventArgs e) { string recordId = RecordId; string tableName = TableName; // Perform the delete operation based on the tableName and recordId // Example: DeleteRecordById(tableName, recordId); } } } Include the User Control in Your Web Forms Include the DeleteModal User Control in your Web Forms (e.g., Department and Banks) and configure it dynamically based on the context. Web Form: Department.aspx Web Form Code-Behind: Department.aspx.cs protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { // Example usage DeleteModal1.DeleteMessage = "Are you sure you want to delete this department?"; DeleteModal1.TableName = "Department"; } } // Function to open modal with specific record ID protected void ShowDeleteModal(string recordId) { DeleteModal1.RecordId = recordId; ScriptManager.RegisterStartupScript(this, GetType(), "showDeleteModal", "$('#modal_Delete').modal('show');", true); } Web Form: Banks.aspx Web Form Code-Behind: Banks.aspx.cs protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { // Example usage DeleteModal1.DeleteMessage = "Are you sure you want to delete this bank record?"; DeleteModal1.TableName = "Banks"; } } // Function to open modal with specific record ID protected void ShowDeleteModal(string recordId) { DeleteModal1.RecordId = recordId; ScriptManager.RegisterStartupScript(this, GetType(), "showDeleteModal", "$('#modal_Delete').modal('show');", true); } This approach allows you to maintain a single instance of the modal code and dynamically handle deletions based on different contexts.

To make a delete modal dynamic in ASP.NET C#, you can follow these steps: Create a Modal in Your ASPX Page or User Control : Define a modal in your ASPX page or User Control. Ensure it has placeholders for dynamic content. × Cancel Delete Trigger the Modal with Dynamic Data : Use JavaScript to populate the modal with dynamic data when a delete button is clicked. function showDeleteModal(recordId, recordName) { // Set the modal title or any other dynamic content document.getElementById(' ').innerText = "Are you sure you want to delete " + recordName + "?"; // Set the hidden field value to the record ID document.getElementById(' ').value = recordId; // Show the modal $('#modal_Delete').modal('show'); } Add a Delete Button in Your HTML Table : Ensure each row in your HTML table has a delete button that calls the JavaScript function with the appropriate parameters. Handle the Delete Action in Code-Behind : In your code-behind file, handle the delete action when the LinkButton is clicked. protected void lnkRecordDelete_Click(object sender, EventArgs e) { string recordId = HiddenFieldRecordId.Value; // Perform the delete operation using the recordId // Example: DeleteRecordById(recordId); } By following these steps, you can create a dynamic delete modal that updates based on the record selected for deletion. This approach ensures that the modal displays the correct information and performs the appropriate action when the delete button is clicked. Thanks

You can write the lnkRecordDelete_Click event handler in either a User Control or a WebForm, depending on your application’s structure and where the delete functionality is needed. Here’s a brief overview of both approaches: 1. In a WebForm (ASPX Page) If the delete functionality is specific to a single page, you can place the code directly in the WebForm’s code-behind file (e.g., Default.aspx.cs ). Example: ASPX Page: Delete Code-Behind (Default.aspx.cs): protected void lnkRecordDelete_Click(object sender, EventArgs e) { string recordId = HiddenFieldRecordId.Value; // Perform the delete operation using the recordId DeleteRecordById(recordId); } private void DeleteRecordById(string recordId) { // Your delete logic here } 2. In a User Control (ASCX) If the delete functionality is reusable across multiple pages, it’s better to place the code in a User Control. Example: User Control (MyUserControl.ascx): Delete Code-Behind (MyUserControl.ascx.cs): protected void lnkRecordDelete_Click(object sender, EventArgs e) { string recordId = HiddenFieldRecordId.Value; // Perform the delete operation using the recordId DeleteRecordById(recordId); } private void DeleteRecordById(string recordId) { // Your delete logic here } Including User Control in a WebForm: Thanks

Hi Ramco, The lnkRecordDelete_Click event handler code should be written in the code-behind file of the Web Form or User Control where the delete modal is used. Here's a breakdown to help determine where this code should be placed: 1. If the Modal is Defined in a User Control User Control Code-Behind: If the modal is part of a User Control (.ascx), and the LinkButton is inside that User Control, then lnkRecordDelete_Click should be defined in the User Control’s code-behind file. User Control File: YourUserControl.ascx User Control Code-Behind File: YourUserControl.ascx.cs // UserControl Code-Behind protected void lnkRecordDelete_Click(object sender, EventArgs e) { string recordId = HiddenFieldRecordId.Value; // Perform the delete operation using the recordId // Example: DeleteRecordById(recordId); } 2. If the Modal is Defined in a Web Form Web Form Code-Behind: If the modal is directly included in the Web Form (.aspx), then lnkRecordDelete_Click should be defined in the Web Form’s code-behind file. Web Form File: YourWebForm.aspx Web Form Code-Behind File: YourWebForm.aspx.cs // WebForm Code-Behind protected void lnkRecordDelete_Click(object sender, EventArgs e) { string recordId = HiddenFieldRecordId.Value; // Perform the delete operation using the recordId // Example: DeleteRecordById(recordId); } Where to Place the JavaScript Function The JavaScript function to set the dynamic data for the modal should be placed in the tags within the ASPX page or within a linked JavaScript file. If the modal is in a User Control, ensure that the JavaScript is included in the parent page or User Control where the modal is used.

Hi Ramco, To make a delete modal dynamic in ASP.NET with C#, you can pass dynamic data (like the ID of the item to delete) to the modal when it is triggered. This allows the modal to confirm the deletion of specific items without needing to create a separate modal for each item. Here's a step-by-step guide: 1. Create the Modal in Your ASPX Page Define the modal once in your ASPX page. You can include placeholders for dynamic content. Delete Confirmation &times; Cancel Delete 2. Triggering the Modal with Dynamic Data You can use a button or link in a GridView or a Repeater control to trigger the modal. The key is to pass the unique identifier of the item you want to delete. ')">Delete 3. JavaScript to Handle Dynamic Data Use JavaScript to set the dynamic data (e.g., the ID of the item) in the modal when it is triggered. function setDeleteItem(id) { // Set the ID to a hidden field or directly to the button command argument document.getElementById(' ').value = id; // Optionally, update the message in the modal document.getElementById(' ').innerText = "Are you sure you want to delete item with ID " + id + "?"; } 4. Handle Deletion in Code-Behind In the code-behind (C#), handle the deletion logic when the delete button is clicked. protected void btnConfirmDelete_Click(object sender, EventArgs e) { string idToDelete = hiddenField.Value; // Perform the deletion logic, e.g., remove from database // Example: // DeleteItemById(idToDelete); // Optionally, rebind the data to reflect the deletion // BindData(); // Close the modal and show a success message, if needed } 5. Hidden Field for Passing Data Use a hidden field to store the ID of the item to be deleted, which will be set by the JavaScript function. Summary Create a reusable modal that will display the delete confirmation message. Pass the ID of the item to be deleted using a JavaScript function. Handle the deletion logic in the server-side code-behind when the delete button is clicked. This approach ensures that the delete modal is dynamic and can be used to delete different items based on the ID passed to it.
